This is not legal JSP (or XML) syntax. You cannot use an element as the
value of an attribute.

That depends on how the <forum:hasContent> tag is implemented. If that is
your own tag, and you are free to modify it, you could EL-enable that tag,
which would allow you to do:
<forum:hasContent content="${attribute}"/>
A good example of how to EL-enable tags can be seen in the Struts-EL tag
library, the source code for which is available here:
http://cvs.apache.org/viewcvs.cgi/jakarta-struts/contrib/struts-el/
On the other hand, if the <forum:hasContent> tag is not under your control,
then you're probably stuck with providing a scripting expression (rtexpr),
which would look just like the example you give above.
