Yes, that is certainly suitable, but check out my earlier post 
showing how to do this with an attribute value template.

I see above you have included the quote, and that is good as I 
explained.  Note that since you are in #PCDATA in your stylesheet, 
you don't need to escape it, and the following would have worked just 
as well (and not needing you to change what you have):

 <fo:basic-link  color="blue">
  <xsl:attribute name="external-destination">
   <xsl:text/>uri("<xsl:value-of select="Heading/@file"/>")<xsl:text/>
  </xsl:attribute>
  <xsl:value-of select="Heading"/>
 </fo:basic-link>

It certainly isn't at XSLT time.  It is a syntactic convention at 
XSL-FO time ... I don't think anything is actually "called" 
though.  As you don't have it in a select= and you don't have it in 
an attribute value template "{}", it is just text with parentheses in 
it from XSLT's perspective.

I hope this helps.
