Hi,

The reason why it's not working (I guess) is this:
>             <xsl:variable name="LineItem">
<snip />
>                 <xsl:apply-templates
> select="RequestQuoteItemDetail/BaseItemDetail/ListOfItemReferences/ListO
> fReferenceCoded/ReferenceCoded" mode="BidLineItems">
<snip />
>             </xsl:variable>
>

This will make the LineItem variable of type Result Tree Fragment, instead
of nodeset.
On top of that, even if it were a nodeset, the following expression
> select="concat($LineItem,'|')" />

will return you the string value of the first node in the set followed by a
'|', not repeat the steps for all nodes in the LineItem nodeset.

So, to get you closer to a solution, be sure to convert the variable into a
nodeset if you're going to apply-templates to it (or perform other
operations on it than simply copying it to your result tree). Use the
node-set() extension function for that (either the processor-specific or
EXSLT's).

Shorthand pseudocode:

<xsl:stylesheet ..
  xmlns:ext="http://exslt.org/common"
  exclude-result-prefixes="ext">
..
<xsl:variable name="LineItem">
  <xsl:apply-templates select="/{full-path}/ReferenceCoded"
                       mode="BidLineItem" />
</xsl:variable>
..
<!-- LineItem is of type RTREEFRAG, so convert first -->
<xsl:variable name="nsLineItem" select="ext:node-set($LineItem)" />

I would also change the BidLineItem-moded template to construct a temporary
tree like:

<xsl:template match="ReferenceCoded" mode="BidLineItems">
  <xsl:param name="fieldName"/>
  <xsl:if test="ReferenceTypeCodedOther='QuestBidExtendedAttribute'">
    <xsl:if test="PrimaryReference/Reference/RefNum=$fieldName">
      <val>
        <xsl:value-of select="SupportingReference/Reference/RefNum"/>
      </val>
    </xsl:if>
  </xsl:if>
</xsl:template>

Then you can do something like the following to construct your attribute:

<xsl:attribute name="ExtAttDefObjLink">
  <xsl:for-each select="$nsLineItem/val">
    <xsl:choose>
      <xsl:when test="not( position() = last() )">
        <xsl:value-of select="concat(.,'|')" />
      </xsl:when>
      <xsl:otherwise>
        <xsl:value-of select="." />
      </xsl:otherwise>
  </xsl:for-each>
</xsl:attribute>


Hope this helps!

Cheers,

Andreas
