Are getter methods mandatory on Tag impls? When are they used?

Thanks,
Bob

Subclassing is certainly one common use case.  Another is when you use
nested tags, and need to access configuration properties set in the
"outer" tag from an "inner" tag.

The JSP container itself does not use the getters, however.

Getters allow you to encapsulate the property which value is being
retreived, i.e. when you subclassing BodyTagSupport for example it comes
with support for "id" property, so you can just getId() to retreive it's
value, so the same way if somebody is going to subclass your
tag handler they should have access to getFoo() instead of accessing 'foo'
field directly...

I hope this is the correct explanation, if not please correct me :)
