Section 5.1 Minimal Conformance contains the following:

2. A definition of every item specified to be implementation-defined, unless that item is part of an optional feature that is not supported by the implementation. A list of implementation-defined items can be found in D Implementation-Defined Items.

Note:

Implementations are not required to define items specified to be implementation-dependent.

3. Support for [XQuery and XPath Data Model (XDM) 3.0], as specified in 5.3 Data Model Conformance.

4. Support for all functions defined in [XQuery and XPath Functions and Operators 3.0].



Bullet 2 appears to require a definition of every implementation-defined item that appears only XQuery 3.0. This is somewhat supported by the non-normative note in D Implementation-Defined Items, which says:

"Additional implementation-defined items are listed in [XQuery and XPath Data Model (XDM) 3.0] and [XQuery and XPath Functions and Operators 3.0]."


I suggest that bullets 3 and 4 be modified:

3. Support for [XQuery and XPath Data Model (XDM) 3.0], as specified in 5.3 Data Model Conformance. [Insert: and a definition of every item specified to be implementation-defined, unless that item is part of an optional feature that is not supported by the implementation.]

4. Support for all functions defined in [XQuery and XPath Functions and Operators 3.0]. [Insert: and a definition of every item specified to be implementation-defined, unless that item is part of an optional feature that is not supported by the implementation.]
