Thanks Michel, but it seems not to work. The tests I've done show that
all depends on the class variable "blockContinuations", if present the
__init__ method receives a blocks sequence, if not returns a string with
the tag arguments.

I've read the source (DT_String and DT_HTML) and it confirms the tests.

The parse seems to be done before the call to __init__ based on
"blockContinuations". Now I'm almost sure that this is not possible,
but perhaps somebody knows a workaround that I haven't noticed.

If somebody knows how to do that I'd be very grateful.

Thanks,
david
