Hi Ken --

Many thanks for the link to your book.  I decided to go with the pull model
as, rightly or wrongly, I felt slightly more in control.  I ditched the inline
data so I could generate a link to the full data contents for each fix. But I
couldn't find a way of doing that *under* the for-each whilst still retaining
access to the @href.  So I ended up with the following which, whilst it works,
is presumably reading the linked document twice just to extract the fix number
and fix abstract:


        <ul>
          <xsl:for-each select="fix">
            <!-- <xsl:for-each select="document( fix/@href )/fix"> -->
            <li>
              <a>
                <xsl:attribute name="href">
                  <xsl:value-of select="@href"/>
                </xsl:attribute>          
                <xsl:value-of select="document( @href )/fix/number"/>
              </a>
              <br/><xsl:value-of select="document( @href )/fix/abstract"/>
            </li>  
          </xsl:for-each>
        </ul>

I'm sure there's a more efficient way, yes?
