1 Introduction

This specification defines a syntax for a generic conformance suite test. Specific types of tests will need to customise this generic conformance suite test to support documentation of the specific inputs and outputs being tested.

1.1 Background

This specification is intended to support the creation, maintenance, and publication of XBRL conformance suites.

1.2 Relationship to other work

This specification works with the XBRL registry specification.

1.3 Language independence

The official language of XBRL International's own work products is English and the preferred spelling convention is UK English.

1.4 Terminology

This specification is consistent with the definitions of any of the terms defined in specifications that it depends on.

1.5 Document conventions (non-normative)

Documentation conventions follow those set out in the XBRL Variables Specification [VARIABLES].

1.6 Namespaces and namespace prefixes

Namespace prefixes [XML NAMES] will be used for elements and attributes in the form ns:name where ns is the namespace prefix and name is the local name. Throughout this specification, the mappings from namespace prefixes to actual namespaces is consistent with Table 1.

The prefix column in Table 1 is non normative. The namespace URI column is normative.

Table 1: Namespaces and namespace prefixes
Prefix Namespace URI
conf http://xbrl.org/2008/conformance
confe http://xbrl.org/2008/conformance/error
xml http://www.w3.org/XML/1998/namespace
xlink http://www.w3.org/1999/xlink

2 Syntax

This specification only provides a textual declaration of syntax constraints when those constraints are not expressed by the normative schema supplied with this specification.

Explanations of elements and attributes are only supplied when explanations are not already provided in other specifications.

Unless explicitly stated otherwise, a reference to a specific element MUST be read as a reference to that element or to any element in its substitution group .

2.1 Attributes in the XML namespace

Any attribute in the XML namespace (http://www.w3.org/XML/1998/namespace) MAY be used on any element within a test case.

The @xml:lang attribute MAY be used to indicate the language used to express information in the test case, as per the XML Specification [XML].

The @xml:base attribute MAY be used when resolving URIs as per the XML Base Specification [XMLBASE].

2.2 Element: testcase

A test case is an XML resource with the <conf:testcase> element as its root.

2.2.1 Element: owners

The optional <conf:owners> element contains one or more <reg:owner> elements, as defined in the XBRL registry specification [REGISTRY].

Each owner is a person with responsibility for maintaining the test case. Without using this element, test case history relies upon information in the source control system being used.

2.2.2 Element: number

The <conf:number> element contains the identifying number of the conformance suite test. That number SHOULD be unique among all tests in the entire suite.

2.2.3 Element: name

The <conf:name> element contains a brief name of the test case

2.2.4 Element: documentation

The <reg:documentation> element contains either a URL that resolves to documentation of the test case or it contains XHTML [XHTML] markup documenting the test case.

2.2.5 Element: reference

The <conf:reference> element contains a link to a a part of a specification that is relevant to the test case.

The <conf:reference> element contains an @xlink:type attribute that equals simple and an @xlink:href attribute that contains a URI that MUST resolve to the part of the specification being referenced.

The <conf:reference> element MAY contain string content documenting the nature of the resource that the URL is linking to.

A test case MAY contain several references, if the test case addresses several aspects of a specification or several specifications.

2.2.6 Element: variation

A test case variation is an XML resource with the <conf:variation> element as its root.

The <conf:variation> element contains the information about a specific variation of the test case.

A test case variation contains many of the same elements as a test case. In particular, it MAY contain its own elements documenting the owners, its number and name, its own documentation, and its references to normative specifications. All of these except for the documentation are optional. The syntax for all of this information matches that for the same information at the level of the test case.

Each test case variation also documents its specific inputs and expected outputs.

2.2.6.1 Element: inputs

The <conf:inputs> element contains a list of elements, one per input to the test case variation.

Each element in a <conf:inputs> element MUST be in the substitution group for the abstract <conf:input> element. This enables different kinds of conformance suites to specify appropriate kinds of inputs.

The syntax for the input files is defined as part of the generic conformance test syntax because input files are common to a broad range of conformance suite tests.

2.2.6.1.1 Input files

Three different kinds of input files are defined as inputs to function test case variations. Input schema files are identified by a <conf:schema> element; input linkbase files are identified by a <conf:linkbase> ; and input instance files are identified by a <conf:linkbase> element.

All three of these elements have the same content model.

The @id attribute is required on all of them to enable them to be referenced by other parts of the test case variation.

If the elements have a @readMeFirst attribute equal to true then they are a starting point for the DTS discovery process that MUST occur as part of initialising the software to perform the test case variation. Otherwise the file MUST NOT be used as a starting point for the DTS discovery process.

The elements also contain an @xlink:type attribute that equals simple and an @xlink:href attribute that contains a URI that MUST resolve to the file that it identifies.

The elements MAY contain string content documenting the nature of the resource that the URL is linking to.

2.2.6.2 Element: outputs

The <conf:outputs> element contains a list of elements, one per output from the test case variation.

Each element in a <conf:outputs> element MUST be in the substitution group for the abstract <conf:output> element. This enables different kinds of conformance suites to specify appropriate kinds of outputs.

2.2.6.2.1 Output error codes

Syntax for an output QName error code is provided as part of the generic conformance test syntax because of the general need for such codes.

Output error codes are expressed by the <conf:error> element. Its QName value is the QName of the error code that MUST be produced by software running the conformance suite test if the software is to pass the test.

2.2.7 Element: revisions

The optional <reg:revisions> element conforms to the XBRL registry specification [REGISTRY]. It provides a syntax for tracking explanations of changes to the conformance suite tests. This is intended to augment the information captured in source control systems, should such augmentation be required.

Appendix A Normative schema

The following is the XML schema provided as part of this specification. This is normative. Non-normative versions (which should be identical to these except for appropriate comments indicating their non-normative status) are also provided as separate files for convenience of users of the specification.

NOTE: (non-normative) Following the schema maintenance policy of XBRL International, it is the intent (but is not guaranteed) that the location of non-normative versions of these schemas on the web will be as follows:

  1. While any schema is the most current RECOMMENDED version and until it is superseded by any additional errata corrections a non-normative version will reside on the web in the directory http://www.xbrl.org/2008/ - during the drafting process for this specification this directory should contain a copy of the most recent published version of the schema at http://www.xbrl.org/2008/conformance.xsd.
  2. A non-normative version of each schema as corrected by any update to the RECOMMENDATION will be archived in perpetuity on the web in a directory that will contain a unique identification indicating the date of the update.
