Keep also in mind that Xalan has its own Formatters.
I welcome your proposal because it goes toward the direction of removing
overlaps between projects.

I vote +1 to the idea, but I would like to see a deeper proposal on all
the "formatting" capabilities from going to the SAX/DOM world to a
stream. Also FOP is into this.

Alternatives are:
1) put printers inside the parser (as Assaf proposes)
2) put printers inside the processor (as it is today)
3) put printers inside FOP
3) create a new project
What do you think?
