Re: in-document references

   <xsl:template match="ref">
     <li>Ref:
       <b><xsl:value-of select="@name"/></b>
       <ul>
         <xsl:apply-templates
               select="//define[@name=current()/@name]"
               mode="def"/>
       </ul>
     </li>
   </xsl:template>

Your current select expression tells the processor to select all 'define'
nodes that are descendants of the document element.

<!--This is a Relax NG schema-->
<grammar>
	<element name="Id">
			<ref name="string"/>
	</element>
	<define name="string">
			<data type="string"/>
	</define>
</grammar>

  <xsl:template match="element">
    <li>Element:
          <xsl:value-of select="@name"/>
          <ul>
            <xsl:apply-templates/>
          </ul>
    </li>
  </xsl:template>

 <xsl:template match="ref">
    <li>Ref:
      <b><xsl:value-of select="@name"/></b>
      <ul>
        <xsl:apply-templates
              select="//define[@name=current()/@name]"
              mode="def"/>
      </ul>
    </li>
  </xsl:template>

  <xsl:template match="define" mode="def">
    <xsl:apply-templates/>
  </xsl:template>

==================output should be===============
(ignoring whitespace issues)

<li>Element: Id
    <ul>
      <li>Ref: <b>string</b>
        <ul>
          <li>
                 Id   <!--This is the hard part-->
          </li>
	  </ul>
    </ul>
</li>
<li>
  [Define: <b>string</b>]
</li>

<li>Element: Id
    <ul>
      <li>Ref: <b>string</b>
        <ul>
          <li>
                 <!--I get nothing here since there is no "element"
                   parent of "define" in the data-->
          </li>
	  </ul>
    </ul>
</li>
<li>
  [Define: <b>string</b>]
</li>

To select just
descendants of the context node, do:

<xsl:apply-templates select=".//define[@name=current()/@name]" mode="def"/>

(This doesn't address optimization of course--this search pattern can be
quite expensive.)
