DOCBOOK-APPS: Using entities (or DSSSL) to INCLUDE / IGNORE text

Hi!

With nsgmls and jade/openjade I can pass a command line parameter to
make an entity have it's option as INCLUDE. I need to change that
behaviour for some documents to make it define then as IGNORE. There
seems to be no option to do that in jade/openjade at convertion time. 
Is it possible?

Some DSSSL hack to achieve the same behaviour is also acceptable, but
it should work approximately the same way.

Thanks!
