You should also be aware of the long-hand way to make elements and  
attributes (from memory, verify details with your favorite reference):

<xsl:element name="a">
     <xsl:attribute name="href"><xsl:value-of select="link"/></ 
xsl:attribute>
</xsl:element name="a">

And, in case you are actually generating XHTML, xsl:element and  
xsl:name have a namespace attribute. Oh, you can also attempt:

<a>
     <xsl:attribute name="href"><xsl:value-of select="link"/></ 
xsl:attribute>
</a>

The <a> node is created in the output document, and the attribute is  
added to the node. I can't remember if you have to be generating XML  
for this to work.
