Today, an XSL discovery relating to relative URLs:

Let's say that in an XSL document you specify an HREF tag like this:
<a href="../../SQCTable.aspx" target="_blank">

And you reference the XSL document from:
http://localhost:3886/sad/CONTENT/

What you want the user to get is:
http://localhost:3886/sad/SQCTable.aspx

Instead what the user gets, because xsl doesn't do relative references, is: http://localhost:3886/sad/CONTENT/sad/SQCTable.aspx
So how do you include a relative url in an xsl document? Well one way is to use xsl:attribute like this:

<a>
   <xsl:attribute name="href">
       ../../SQCTable.aspx
   </xsl:attribute> 
   SQCTable.aspx
</a>
