all you need is something in your xml file like:
<attribute>
<name>attributeName</name>
<required>{true/false}</required>
<rtexprevalue>true</rtexprvalue>
</attribute>
by default, <rtexprvalue> is false, which requires your attribute value to be a
fixed string. i think you only need to deal with TagExtraInfo if you want to do
some validation.
i highly recommend checking out
http://developer.java.sun.com/developer/Books/cservletsjsp/chapter14.pdf for a
great tutorial on custom tags.
