I've have a set of <class> nodes. They may have <association> children which
in turn have a 'target' attribute with the name of other classes. So,
basically, some classes are associated with other classes.

I would like to seed a stylesheet with the name of a class and then have it
traverse the associations through the classes.

I've got one stylesheet 'report-subgoals-list' that calls another stylesheet
'subgoals-list' and passes a class-name parameter. Iterating though its
<association>s, each one's target value is displayed, and then the
"subgoals-list' stylesheet is called in an attempt to recursively traverse
the associations. Note: the associations are NOT circular.

Here's the call from the 'report-subgoals-list' stylesheet:

  <xsl:call-template name="subgoals-list">
    <xsl:with-param name="class-name">XYZ</xsl:with-param>
  </xsl:call-template>

and of the essence of the 'subgoals-list' stylesheet:

  <xsl:for-each select="//class[@name= $class-name]">
    <xsl:for-each select="association">
      <div class="generaltext"><xsl:value-of select="@target"/></div>
      <xsl:if test="//class">
        <xsl:call-template name="subgoals-list">
          <xsl:with-param name="class-name"><xsl:value-of
select="@target"/></xsl:with-param>
        </xsl:call-template>
      </xsl:if>
    </xsl:for-each>
  </xsl:for-each>

These stylesheets do produce output but it's difficult to interpret their
success since all targets are rendered similarly. Ideally, I'd like to
indent a list of targets relative to their parent. Any thoughts as to how
this could be done assuming a indeterminate number of indentations would be
really appreciated.

FYI, I'm using a processor that supports only XSL 1.0.

Thanks in advance,
David
