Sort of, though not a function, exactly. But if you can't rewrite FuncA to 
be context-neutral, you can work around it by switching context ad hoc, 
with a for-each (or even an apply-templates with a mode):

<xsl:template name="FuncB">
  <xsl:param name="cur-node" select="."/>
  ... whatever you do ...
  <xsl:for-each select="$cur_node">
    <xsl:call-template name="FuncA"/>
  </xsl:for-each>
  ... whatever else ...
</xsl:template>

I hope that helps,
Wendell
