True.  That was the first thing I checked but the rtexprvalue is set to
"true" already and it doesn't make any difference:

<tag>
  <name>link</name>
    <attribute>
      <name>href</name>
      <required>false</required>
      <rtexprvalue>true</rtexprvalue>
    </attribute>

Thanks again!

The spec says:  rtexprvalue <=> scriptlets

I thought that you can use a custom tag as an attribute value for
another
tag, provided the attribute is designated within the TLD file as being
<rtexprvalue>true</rtexprvalue>.
