Re: [Gestalt-users] [ gestalt-Bugs-1563054 ]gexslt:transformation() and namespace bindings

[Colin A. <col...@ho...>]

It is absolutely correct for function-available(gexslt:transformation) to 
return false for use-when processing. This is required behaviour.

It is also correct for the function to be available at run time (though not 
required).

So, no bug, just a user error.

At least, I think this is the case. In XSLT 2.0 section 3.12, it says:

"In scope functions The core functions defined in [Functions and Operators], 
together with the functions element-available, function-available, and 
system-property defined in this specification, plus an 
implementation-defined set of extension functions. Note that stylesheet 
functions are not included in the context, which means that the function 
function-available will return false in respect of such functions. "

But this doesn't seem to be useful to me. function-available ought to 
indicate which functions are unavailable at runtime, for it to be useful to 
call it in a use-when attribute.
So I think this is a bug in the spec.

If you agree with this, then please raise a bug on the W3C bugzilla.
