Re: xsl:key in a function?

As a matter of fact is it even even possible to have xsl:key in a
custom function?

It's not clear what you mean by custom function gere, do you mean an
xsl-defined function using xsl:function, or an extension function?

In the former case, you can use a key, but as in templates they key()
function is used in the function or template, but xsl:key is a top level
declaration that is always a child of xsl:stylesheet.
