Dear Martin Duerst,

in
http://lists.w3.org/Archives/Public/www-xml-query-comments/2000Jul/0000.html
,
you have posed a number of comments on the requirements document of
the XML Query Working Group, Version January 31
(http://www.w3.org/TR/2000/WD-xmlquery-req-20000131)

This response ammends our response in
http://lists.w3.org/Archives/Public/www-xml-query-comments/2000Aug/0021.html
with respect to some of the open comments.

Ad Comment "e":

You wrote
<cite>
e. 3.4.14 to 3.4.16: why "SHOULD" rather than "MUST"?
</cite>

As for the SHOULD requirement 3.4.15 (Operations on Schemas)
the XML Query WG agrees that certain operations on schemas
are a MUST. Therefore, the following MUST requirement
will be added in the next version of the document:

3.4.x Operations on Schema PSV Infoset

   Queries MUST be able to operate on information items provided
   by the post-schema-validation information set defined by XML Schema.

(for 3.4.14 and 3.4.16 please see our previous response
http://lists.w3.org/Archives/Public/www-xml-query-comments/2000Aug/0021.html
)

The other open comments a, l, m need further discussion.
We hope to resolve them at our next F2F together with the I18N group:
<cite>
a. The XML Query language should work equally well with any data or
   query, regardless of the (human) languages or locales involved.
   (This does not imply automatic translation!)
l. The data model must account for inherited attributes (such as
   xml:lang).
m. Query processors need to know about the structure of xml:lang. If
   a query asks for a match of the string "chat" with xml:lang="fr",
   the query should match data with xml:lang="fr-BE". Note: the
   language tag spec, RFC 1766, is currently being extended (3-letter
   language codes being introduced). The XML 1.0 spec has been
   amended to take this into account.
</cite>

All the best,

Peter Fankhauser
