Re: Response to XSL WG comments

The XML Query Working Group has further discussed
its response to Comment-26 (see also:
http://lists.w3.org/Archives/Public/www-xml-query-comments/2000Jun/0001.html
)
of the XSL Working Group on the XML Query Requirements Document,
Version January 31/2000
(http://www.w3.org/TR/2000/WD-xmlquery-req-20000131),
and agreed on the following revised response and
action:

XSL-Comment-026: Relationship to XSTL/XPointer/XPath
-----------------------------------------------------

In Section "Comments by Section" the XSL-WG writes:
<comment>
"XSL, XPointer" should be separated into XSL, XPath, and XPointer. XPointer
is defined by a working group separate from the XSL WG. XPath is a
Recommendation used by both XSLT and XPointer.

The "XSL, XPointer" paragraph seems to imply that the XML Query group will
try to duplicate the functionality of XPath when formulating its language,
but is not committed to using it, i.e. it reserves the possibility of
creating its own language. The XSL WG urges that both XPath and XSLT be
used as the syntactic basis for the XML Query Language, not merely as its
functional basis.

<requirements>
XSL, XPointer

Both XSLT and XPointer use XML Path Language (XPath), which defines a
location path syntax that can be used to search for matching parts of an
XML document. The XML Query work will take into consideration the
expressibility and search facilities of XPath when formulating its algebra
and query syntax, and wherever possible try to encompass those
functionalities into its query language.
</requirements>

XML Query WG response: The next version of the requirements
document will ammend the above paragraph with explicit consideration
of XSLT and XPointer as follows:

<newversiop>
XSL and Linking Working Groups

Both XSLT and XPointer use the XML Path Language (XPath),
which defines a location path syntax that can be used to search for
matching parts of an XML document. The XML Query work will take into
consideration the expressibility and search facilities of XPath when
formulating its algebra and query syntax, and where desirable try to
encompass those functionalities into its query language.  The XML Query WG
will also take into consideration the additional functionality in the XSLT
and XPointer specifications.
</newversion>

All the best,

Peter Fankhauser
