RE: [bug 5070] Requirement for validator to implement deref()

Does anyone disagree with the proposal to add the following explicit requirement in the Conformance section ?

The validator MUST provide an implementation of the deref() XPath extension function.

Hi Sandy,
Are you opposing the proposal or seeking clarification?


------- Comment #6<http://www.w3.org/Bugs/Public/show_bug.cgi?id=5070#c6> From Sandy Gao<mailto:sandygao@ca.ibm.com> 2007-10-25 17:52:29 [reply<http://www.w3.org/Bugs/Public/show_bug.cgi?id=5070#add_comment>] -------

I'm not sure what this would mean.



An SML processor/validator takes an SML model as input, and produce results

about its validity and apply schema/schematron rules. What does it mean for it

to provide a deref() implementation? That can be used outside of the context of

SML validation?



Note that this is an XPath function. Are we imagining that some XPath

processing is performed after the model is validated, and the XPath engine can

use the validator's deref() implementation when evaluating XPaths?

A deref() function is required for validation. One cannot evaluate SML identity

constraints and schematron constraints without it.



The proposal simply says that we should explicitly state this requirement in

the conformance section.

Another easy one to agree on! Please speak up if you disagree.

Proposal:
Add the following line to section "7. Conformance Criteria"

The validator MUST provide an implementation of the deref() XPath extension function.
