Q: Attribute value templates

Is there some way to insert the result of an attribute value template 
into the character content of an element in the result tree?  I need to 
do this because certain syntax, in particular arg() and constant(), 
is only allowed in an attribute value template.

Specifically, I'm trying to write a macro that takes a filename as an 
argument and generates an HTML <A> element with an href based on the 
filename (that part's no problem), and with the filename as the content:

<xsl:macro name="file-link">
  <xsl:macro-arg name="file-name"/>
  <A href="{constant(base-url)}/{arg(file-name)}">
<!-- How can I insert file-name here? -->
  </A>
</xsl:macro>

Thanks for any help.
