[xslt] Support of EXSLT function

[Damien POBEL - Kaliop <dpobel kaliop com>]

Hello,

I'm using XSLT stylesheets with PHP and with xsltproc and I would like 
to know witch functions of EXSLT are supported by libxslt.

For example, str:split() is not marked as supported by libxslt on this page
http://www.exslt.org/str/functions/split/index.html but seems to work in 
xsltproc. Is there a page where I can find updated informations on it ?

Thanks.
