- "cannot" instead of "can not" (meaning "also can")
- "than" instead of "then" (Hint: "then" should hardly be needed;
you're not telling the order in which to do something)
... plus removed a couple ending. dots
- Added possibility to call php functions as XSLT-functions
eg: <xsl:value-of select="php:function('date','r')"/>
Namespace is http://php.net/functions
