If you call document() twice with the same > URI, you should get the same tree back each time. I understand (this is clearly functional), but is this really reasonable? I mean, if the URI is an URL of a dynamic document that changes every time it is getted (e.g. some CGI), then I have no possibility at all of retrieving the newest version. A simple example: we can imagine of implementing a simple CGI that returns an XML page with the root element having a random number attribute. Every document() call should issue a new run of the CGI and return me a new nonce. I currently use this "feature" (but I should say bug!!!!) to implement "xsl-extensions" in a standard (but I should say non-standard!) way. I would prefer this requirement to be got rid of in the XSLT spec. Instead, I would put a special PI (or something similar) telling the XSLT processor that the document retrieved is ever the same. What do you think about this? Am I brain-damaged or what?
