Re: Tags nested in Attribute Values

[Peter Alfors]

It is an admirable goal, but not necessarily an easy one to achieve.
The problem lies (as you pointed out) in the fact that custom tags cannot be
embedded into another one as an attribute.

I think that what you will notice as you move onward is that there are times
when you will want to have a dynamically created attribute for your custom tag.

However, you do have some tricks on your side.  Custom taglibs have the ability
to interact with one another.  A child tag can retrieve attributes that the
parent tag has.
Also, you can use the page/request/etc to store dynamic data that other tags
may need.

You may find yourself writing your own special anchor tag or some other tag to
do what you want.  But in the long run, it is an achievable goal.
You just need to decide how important it is to completely remove all script
from your page.

HTH,
