[xslt] Implementation of unparsed-text() (XSLT 2.0)?

[Daniel Leidert <daniel leidert spam gmx net>]

Hello,

I wanted to ask, if there are any plans to implement the XSLT 2.0
function unparsed-text() [1]. It seems the only possibility to read in
the content of a text-file and assign it to a variable in a XSL
stylesheet. So what is the current policy regarding XSLT 2.0 functions?
