Yes there is a root element MxDOM which I missed in this post. I have it in my
program however.

I am using LotusXSL 0.18.5. Subsequently, I wrote an intermediate XSL that
converted all the attributes of the node to elements. That is

Old XML
=======
<browseList>
    <MxColumn>SUBCODE</MxCOlumn>
    <MxColumn>SUBDESC</MxColumn>
 </browseList>
 ...............
 ...............
 <bookhouse>
   <SUBJECT>
     <row SUBCODE="ANM" SUBDESC="Animal Science"  CREATEDATE="1999-10-10"
CREATEBY"BABY" />
     <row SUBCODE="COM" SUBDESC="Computer Science"  CREATEDATE="1998-12-10"
CREATEBY"XYZ" />
     <row SUBCODE="BIO" SUBDESC="Biology" CREATEDATE="1999-01-05" CREATEBY"ABC"
/>
     <row SUBCODE="GEO" SUBDESC="Geography" CREATEDATE="1999-08-13"
CREATEBY"BABY" />
   </SUBJECT>
 </bookhouse>


New XML
=======

<browseList>
    <MxColumn>SUBCODE</MxCOlumn>
    <MxColumn>SUBDESC</MxColumn>
 </browseList>
 ...............
 ...............
 <bookhouse>
   <SUBJECT>
     <row>
       <SUBCODE>ANM</SUBCODE>
       <SUBDESC>Animal Science</SUBDESC>
       <CREATEDATE>1999-10-10</CREATEDATE>
       <CREATEBY>BABY</CREATEBY>
         </row>
    <row>
       <SUBCODE>COM</SUBCODE>
       <SUBDESC>Computer Science</SUBDESC>
       <CREATEDATE>1998-12-10</CREATEDATE>
       <CREATEBY></CREATEBY>
       </row>
   .... other rows .....

  </SUBJECT>
 </bookhouse>

 With the new XML, Now I am able to select

  bookhouse/SUBJECT/row/SUBCODE and
  bookhouse/SUBJECT/row/SUBDESC

 because these occur under
   /bookhouse/MxColumn

using

   <xsl:for-each select="/bookhouse/SUBJECT/row">
     <xsl:for-each select="*">
               <!--   @* gives error and This works -->
       <xsl:variable name="columnName"
          select="ancestor::MxDOM/browseList/MxColumn/." />

        <xsl:if test='name()=$columnName'>
         <xsl:value-of select=current() />
       </xsl:if>
      </xsl:for-each>
    </xsl:for-each>


Is it a bug (that you cannot traverse the Document using Axes when the context
node is an attribute). then in LotusXSL 0.18.5?
