It's a scope issue: $ItemAStruct exists only within its local template, so
your matching template can't "see" it.

You have two options: make $ItemAStruct a global variable (i.e., move its
xsl:variable declaration outside your templates), or better yet, pass it as
a parameter:

<xsl:apply-templates select="//Content/ItemAs">
  <xsl:with-param name="ItemAStruct"
select="document('lookup.xml')/TableStructures/ItemA"/>
</xsl:apply-templates>

<xsl:template match="ItemAs">
  <xsl:param name="ItemAStruct"/>
  <!-- rest of code -->
</xsl:template>
