+Summary: xslt variables not resolved when in a xpath predicate expression
+
+Description of Problem:
+
+When using XslTransform.Transform, when a variable or parameter is used in
+an xpath predicate expression it is not resolved.
+
+In general,
+
+<xsl:stylesheet ...
+ <xsl:param name="parameter"/>
+ ...
+ <xsl:template ...
+ <xsl:... select="nodelist[@attribute=$parameter]" ...
+
+Results in an error when resolving $parameter.
+
+
+See attachments to reproduce:
+to compile: mcs Test.cs
+to use: mono Test.exe <xsltfile>
+
+Three test cases provided, all should have the same output:
+test
+this is a test
+
+1. A working xslt for demonstration purposes.
+$ mono Test.exe test1.xslt
+test
+this is a test
+
+
+2. An xslt that uses a global parameter within an xpath predicate
+expression.
+$ mono Test.exe test2.xslt
+
