And it won't.
rtexprvalue = true means you can use something like:
<link .... attr=<%=someObject.someproperty(some expressionof any type)[some
index...]%>> or
<link .... attr=<%=some expr of any kind%>>
You can use a Java expression (any) provided the type matches the type
expected by the tag.
You still CANNOT use a tag in an attribute, even with rtexprvalue=true.

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>.
