I get this error in PHP 4.1.1 and 4.1.2 (latest) XSLT mod (aka sablotron)

Sablotron error on line 41: unexpected attribute 'exclude-result-prefixes'

Also i get this error in Xtrans that uses MSXML4.0.

The element 'xsl:transform' is used but not declared in the DTD/Schema.

Can anybody help me solving this crap? i realy hate this, if i make a error i have less problems with then parsers that claim things they are not able to...
