XSLT Parameter scoping problem using .Net and XSLTArgumentList

[Michael]

I am having a problem with scoping of parameters in my XSLT
Stylesheet...here is the stylesheet (the xml document is irrelevant
for the example)

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:param name="myParam">Stylesheet Default</xsl:param>
<xsl:template match="/">
<result_explicit_call>
<xsl:call-template name="test">
<xsl:with-param name="myParam">Explicit Call</xsl:with-param>
</xsl:call-template>
</result_explicit_call>

<result_template_default>
<xsl:call-template name="test"/>
</result_template_default>

</xsl:template>

<xsl:template name="test">
<xsl:param name="myParam">Template Default</xsl:param>
<xsl:value-of select="$myParam"/>
</xsl:template>
</xsl:stylesheet>

The 'Correct' result for this transform (what MSXML4 returns) is...
<result_explicit_call>Explicit Call</result_explicit_call>
<result_template_default>Template Default</result_template_default>

However if I do it in .Net Version 1.1.4332 and pass down a new
parameter using xsltargument list ('Passed in'), it blows away all my
local scoping of the parameter...
<result_explicit_call>Passed in</result_explicit_call>
<result_template_default>Passed in</result_template_default>

Is this a known issue?? Is there a workaround??

Any help appreciated.

Seems like a bug. I've simplified stylesheet to this one:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:param name="param"/>
<xsl:template match="/">
<xsl:variable name="param" select="'Shadowing value'"/>
<xsl:value-of select="$param"/>
</xsl:template>
</xsl:stylesheet>

Here local variable "param" in the template must shadow any namesake global
variables and parameters, so the result must be "Shadowing value" anyway.

I've tested it under .NET 1.1. Results are:
1. No parameter value passed into transformation:
"Shadowing value"
2. "Passed in" parameter value passed into transformation:
"Passed in"

That's interesting to note that default parameter value doesn't affect
shadowing - it works as it should, but when passing actual parameter value it
breaks shadowing.
