RE: [xsl] A list of useful functions that aren't in the core of xsl.

["bryan" <bry@xxxxxxxxxx>]

This is because they(the fxsl stylesheets) depend on a node-set()
function which is an extension function under xslt 1.0

Exslt has a node-set() function in the exsl namespace so that one could
be processor independent, at least if processors used support exsl.

The native xalan node-set() function is named nodeset() if I remember
correctly (I keep saying that cause it's a hell of a long time since I
used xalan), which means that it is not name-compatible with others.

Most processors have node-set() so that if what one needs to do is just
use node-sets one can have the following

ns:node-set($mynode)
and then bind the ns prefix to whichever node-set implementation one
wants. 

Fxsl could have used fallbacks etc., I suppose, to make it all processor
independent, not sure why this wasn't done other than not wasting
processing power.

having just looked at the FXSL sourceforge site, i'm intrigued by
the fact that there are three different .zip files; for MS, Saxon
and Xalan, respectively.

i'm just about to take a look at FXSL, but is there some reason
that functions written in XSLT would need to be processor
dependent?  curious.
