Amazing... one small piece of "borderline flamage" from me (I take the
blame/credit/responsibility ;->) sparks a lively and useful discussion
(15+ messages in this thread now ;->)...

So, proof that there are times when minor "flamage" is not so bad... if
the ends justify it ;->

You can flame me now... I'm already charred beyond recognition, so it
won't hurt so bad ;->

Cheers,
Chris

XPath 1.0 Section 6 says in toto:

"Conformance
XPath is intended primarily as a component that can be used by
other specifications. Therefore, XPath relies on specifications that
use XPath (such as [XPointer] and [XSLT]) to
specify criteria for conformance of implementations of XPath and does
not define any conformance criteria for independent implementations of
XPath."
http://www.w3.org/TR/xpath#section-Conformance 

Also, extension functions are defined in XSLT, not XPath, so neither
adding
operators or functions to the XPath 1.0 spec is any more or less
correct.
If you want a "standard" query language for XML DBMS, wait until XQuery
comes out, (or get the XML world to agree that XSLT is "the" XML query
language, I don't care) then we can argue about each other's
conformance. 

Admittedly, I shouldn't have used the word "conformance" in spinning off
this thread. My point was that in a fluid technology/standards situation
such as we find ourselves in now, "conformance" is less important than
learning what really works. It's time  now to figure out what query
language
syntax/semantics hits the right balance of theoretical rigor,
implementation
efficiency, end-user understandability, and so forth. The argument "I am
more XPath 1.0 conformant than thou" doesn't contribute much to this
process.

If y'all wanna have a religious war, there are plenty of real ones to
choose
from these days, sigh.
