The method generateBody() is meant to "continue to generate
codes for body of the tag, as usual". What you want is a method
to "generate codes to get the body content", which is certainly
doable, but is not currently available. You are welcome to have
the first crack at extending the plugin framework if you like. It'll
require invoking pushBody(), generateBody(), then popBody() to get the
body content, similar to the codes that are being generated for
fragments. But I don't think you really need it though.
Attributes are much simpler, they are just expressions.
BTW, your English is just fine: no apologies needed. :-)
