Re: Comments on GRDDL (using 3rd-party XML schemas with GRDDL) [OK?]

Hi Harry,

This looks good, except for one phrase.

> Furthermore, in addition to being GRDDL-aware, an agent may feature optional capabilities such as allowing a schema and an associated transformation not at the namespace URI to be looked up using a non-standard mechanism,

The phrase "non-standard mechanism" might be interpreted as a mechanism 
not defined in the W3C XML Schema specification, and I think the new 
language is being added at least partly to make sure that the *standard* 
mechanisms such as schema location hints can be used. I'd suggest 
changing this to "allowing a schema and an associated transformation not 
at the namespace URI to be looked up using the mechanisms defined in the 
W3C XML Schema specification."

[For example, a GRDDL-aware agent may have a security policy that prevents it from accessing GRDDL transformations located in untrusted domain names or it may be unable to apply transformations given in a language it does not support, and so it may be unable to produce the faithful rendition. Furthermore, in addition to being GRDDL-aware, an agent may feature optional capabilities such as allowing a schema and an associated transformation not at the namespace URI to be looked up using a non-standard mechanism, and the results of applying such a transformation may not be a faithful rendition.]  In defining these tests it was assumed that the GRDDL-aware agent being tested is using a security policy which does *not* prevent it from applying transformations identified in each test [, supports XSLT 1.0, and does not rely on any capabilities outside those defined in the GRDDL Specification]. Such an agent should produce the GRDDL result associated with each normative test, except as specified immediately below."
