Couldn't you use "org.xml.sax.helpers.AttributesImpl" and do something like
this
AttributesImpl atts;
atts.addAttribute("", "foo", "foo", "ID", "val");

to xalan-dev Subject: Re: Using the id() function with
SAX input
I would be happy to do something like that (although it would be much nicer
to do something global
up front).
However, I'm using the Java version, and I find nothing in the API
corresponding to attrs.addAttribute(). I see lots of methods for _getting_
type information, but none for setting it.
