RE: variable question

Well, I can answer at least the variable scoping issue. 
Global variables are defined in the stylesheet -- not inside
any template, including the template for the root node of
the document. 

Variables only exist within the scope of the template 
that they are defined in -- so your definition is 
only valid within the root node template, but not
any subsequent templates. Do something like this: 

<xsl:stylesheet ...>

<xsl:variable name="BusinessPartnerContract" select="<set the value here>"/>

<xsl:template match="MYROOT">
...
</xsl:template>

and keep your named template. The reference inside the named template
should work now without any other changes.
