> One of the features I used in T4 which made it very powerful was the ability to pass informal parameters to a Block and then get them from within the block. BeanEditForm demonstrates making a context available to blocks via an environmental interface but this seems like too much overhead for less formally defined situations. Perhaps it could look something like this:
> <t:delegate to="block:myblock" foo="bar" />
> <t:block id="myblock">
> ${context.parameters.bar}
> </t:block>
> in the class:
> @Environment
> private BlockContext context;
> the interface:
> public interface BlockContext {
>   Map<String, Object> getParameters();
> }
> This would also required being able to do more OGNL-like expressions.
