Please all, tell why you think it is scriptless before throwing my answer in the bin
From the specification:
body-content:
Specifies the format for the body of this tag.
The default in JSP 1.2 was "JSP" but because this
is an invalid setting for simple tag handlers, there
is no longer a default in JSP 2.0. A reasonable
default for simple tag handlers is "scriptless" if
the tag can have a body.
