RE: [xsl] in-document references

Hi,

You are not using namespaces, eh?

What I do for this is to set a key on the the rng:define's, like:

<xsl:key name="defs" match="rng:define" use="@name"/>

then when you match your rng:ref's you do:

<xsl:apply-templates select="key('defs', @name)/*"/>

For the form problem you posed earlier, you should be able to tell what kind of
form control to use from things like rng:choice = html:select, rng:oneOrMore =
html:input[@type=checkbox] etc... Or use a data type to set form fields, e.g:

  <rng:define name="description">
    <rng:element
      name="description"
      a:label="Description"
      xmlns:dc="http://purl.org/dc/elements/1.1/">
      <rng:data type="token">
        <rng:param name="maxLength">256</rng:param>
      </rng:data>
    </rng:element>
  </rng:define>

Another useful thing to do is use annotations to provide a friendly label and
perhaps a default value among other things, like:

  <rng:define name="language">
    <rng:element
      name="language"
      a:label="Language"
      a:default="en"
      xmlns:dc="http://purl.org/dc/elements/1.1/">
      <rng:choice>
        <rng:value type="NMTOKEN">en</rng:value>
        <rng:value type="NMTOKEN">bg</rng:value>
      </rng:choice>
    </rng:element>
  </rng:define>

and some XSLT (when matching the rng:element):
...
<xsl:when test="boolean(rng:choice)">
  <select id="{$md_name}{$gen_id}" name="{$md_name}{$gen_id}">
    <xsl:for-each select="rng:choice/rng:value">
      <xsl:variable name="value" select="normalize-space(.)"/>
      <option value="{$value}">
        <xsl:if test="$current_nodeset_value=$value">
          <xsl:attribute name="selected">selected</xsl:attribute>
        </xsl:if>
        <xsl:value-of select="$value"/>
      </option>
    </xsl:for-each>
  </select>
</xsl:when>
...

make sense?

best,
