Very Strang XML problem

[Tjerk Wolterink]

Hello i'm using php with xml.

I've an rather big xsl file, that has the following code in it:

<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:styleshe et version="1.0"
xmlns:xsl="http ://www.w3.org/1999/XSL/Transform"
xmlns:page="htt p://www.wolterinkwe bdesign.com/xml/page"
xmlns:menu="htt p://www.wolterinkwe bdesign.com/xml/menu"
xmlns:role="htt p://www.wolterinkwe bdesign.com/xml/roles">

<xsl:output method="xhtml" indent="yes"/>

<xsl:param name="absolute_ url"/>
<xsl:param name="upload_ur l"/>
<xsl:param name="document_ root"/>
<xsl:param name="role"/>
<xsl:param name="xcd_dir"/>

<xsl:variable name="menu" select="documen t(concat($docum ent_root,
'/menu.xml'))"/>
<xsl:variable name="roles" select="documen t(concat($xcd_d ir,
'/roles.xml'))"/>

<xsl:template match="/page:page">
....
...
[cut]

I then transform an xml file (that xml file is not really interesting)
using this xsl. But when i have this line in the xsl:
<xsl:variable name="roles" select="documen t(concat($xcd_d ir,
'/roles.xml'))"/>

I get the following error[sablatron php]:

XSLT Error:

array(4) {
[0]=>
resource(18) of type (XSLT Processor)
[1]=>
int(3)
[2]=>
int(0)
[3]=>
array(6) {
["msgtype"]=>
string(5) "error"
["code"]=>
string(1) "2"
["module"]=>
string(9) "Sablotron"
["URI"]=>
string(26) "C:/webserver/xcd/roles.xml"
["line"]=>
string(1) "1"
["msg"]=>
string(51) "XML parser error 4: not well-formed (invalid token)"
}
}

So i conclusion: roles.xml is not valid xml. But my browser says it is!

And i cannot find the invalid token. Please Help!!!
roles.xml:

<?xml version="1.0" encoding="ISO-8859-1"?>
<roles xmlns="http://www.wolterinkwe bdesign.com/xml/roles">

<!--

It appears that you are trying to call the document function with an
argument "C:/webserver/xcd/roles.xml", which is presumably a windows
file name. The argument to the document function should be a URL,
probably something like "file:///C:/webserver/xcd/roles.xml".
