This document describes the processes whereby entries may be added to, changed, or removed from the XBRL International Data Type Registry. The Data Type Registry is an online listing of data types that have been identified as potentially having wide utility. The Registry contains structured information about their purpose, usage and any intended impact on XBRL instance validation.
This document is based on the processes laid down in [LRR PROCESS].

XBRL provides a set of standard data types that may appear in XBRL schemas. These include those specified in [XBRL 2.1], [DIMENSIONS] and any additional modules that are XBRL RECOMMENDATIONs. As XBRL applications emerge, new, non-standard data types having common and useful semantics are being proposed. The goal of the XBRL Data Type Registry DTR is to be a public, online data set that documents these non-standard data types and their usage. Additions and other changes to the DTR, like other XBRL International work products, are processed through a series of steps detailed in this document. The goal is to maximise the utility and longevity of the new data types and the taxonomies that use them.
The key words MUST, MUST NOT, REQUIRED, SHALL, SHALL NOT, SHOULD, SHOULD NOT, RECOMMENDED, MAY, and OPTIONAL, in this specification, are to be interpreted as described in [IETF RFC 2119].

When referring to a specific element, it will be identified by
its namespace prefix and local name. For example, the root element
of a versioning report would be referred to as
Attributes are also identified by their local name and, where
appropriate, their namespace prefix. Attributes are

The process by which an entry is added to the DTR is described below. This is modelled on [TECH-WG-PROCESSES] but is shortened to reflect the fact that the nature of an DTR entry is significantly less pervasive than that of a specification or other work product that is the usual output of a Working Group.
In addition a "fast track" process is provided whereby data types that do not necessarily have general applicability (and so are unlikely to qualify for RECOMMENDED status) can nevertheless be included in the DTR as "Acknowledged".
The process starts when the submitter creates a submission containing all of the information needed (as specified in [DTR STRUCTURE]) and requests the DTRAM to enter it into the DTR. The submitter MUST indicate whether they are seeking Acknowledged or RECOMMENDATION status. If they are seeking Acknowledged status then the subsequent steps are as detailed in Section 2.1, if they are seeking RECOMMENDATION status then the subsequent steps are as detailed in Section 2.2.
Submitters should note that the initial status of their submission MUST be "PROPOSED" (see [DTR STRUCTURE]).
A "fast track" process is provided to facilitate the inclusion of a data type in the DTR which may not have general applicability but which the submitter would, nevertheless, like to have documented in a publicly accessible fashion. A data type that successfully follows this "fast track" process will have an ending status of "ACK". As such it does not carry the same normative weight as a data type with "REC" status.
A data type that follows this track will have a status that is normative to the extent documented in Section 4 ("Normative Status of Data Types in the DTR and Software") of [DTR STRUCTURE]. Thus the process is, necessarily, considerably more rigorous than for a data type that follows the "fast track" process leading to "Acknowledged status".
The process by which an entry may be updated in the DTR is analogous. If errata are discovered in any data types with "REC" status then a new version of the data type will be entered into the registry following the same process as that used for errata corrections to the specification itself. The effective date of the errata corrected version will be later than that of the original and will thus supersede it.
Unless a data type has the status of "REC" it may be withdrawn from the DTR at any time upon request of the original submitter. Such request MUST be made to the DTRAM by e-mail to the address published at http://www.xbrl.org/dtr.
A data type with the status "REC" MAY NOT be withdrawn in this manner but MUST follow the process in Section 2.4 for rescinding a RECOMMENDED data type.
The process of rescinding a data type is not defined. If a situation arises whereby it becomes necessary to do so it will be defined following the model of [TECH-WG-PROCESSES].
