[XML-SIG] ParserFilter proposal

[Lars Marius Garshol]

| It this how its done in Java by John Cowan? 

No, it's not. I've separated the filter and the DocumentHandler, while
he has the filter implement DocumentHandler, AttributeList and the
other handlers.

He also lacks the factory stuff I did, but has at least settled on a
policy with the other handlers.

See: <URL:http://www.ccil.org/~cowan/XML/ParserFilter.java>


Should we align ourselves with his proposal? It's not turned into a
standard, whether de facto (OK, Simon St.Laurent uses it) or de jure.

| 
| xmlarch could definately be fitted into a ParserFilter.
| 
| I don't see any problems with this at all. Since xmlarch is written as a
| DocumentHandler, only minor modifications would probably have to be done. 
| 
| I originally wrote xmlarch as a wrapper around a Parser object, but soon
| realized that that was overkill. Only XML events from a DocumentHandler is
| needed to write an architectural forms processor.
| 
| The next release of xmlarch is probably going to be independent of SAX.
| I've been thinking of removing the direct connection to SAX, and instead
| make it a more general module. Wrappers/plugins could then be written for
| SAX (both DocumentHandler and ParserFilter), DOM and other kinds of input.
