Question about XSLTransform and extensions

[fawzib.rojas]

I have the following class and function:

class MathExtension{
public double max(double a,double b){
Console.WriteLi ne("math:max("+ a.ToString()+", "+b.ToString()+ ")");
return Math.Max(a,b);
}
}

public void Transform(XmlDo cument xml,XmlDocument xsl){
XPathDocument xp_doc;
XslTransform xsl_trans;
XsltArgumentLis t xslArg = new XsltArgumentLis t();
MathExtension ex=new MathExtension() ;
// add extension
xslArg.AddExten sionObject("xal an://java.lang.Math" ,ex);
// create and load objects
xp_doc=new XPathDocument(n ew XmlNodeReader(x ml));
xsl_trans=new XslTransform();
xsl_trans.Load(
new XmlNodeReader(x sl),null,Assemb ly.GetCallingAs sembly().Eviden ce
);
// do transformation
xsl_trans.Trans form(xp_doc,xsl Arg,new XmlNodeWriter(F Doc,true),null) ;
}

when I do a transformation and use something like:

<xsl:value-of select="my_obj: max(number(@an_ attribute),0.01 )"/>

The first parameter always says "NaN", what am I doing wrong? Is there
a problem with the number() function? is there another way to do it?

What is the context node in that xsl:value-of select expression, does it
have an attribute named @an_attribute, which value does the attribute have?
