XOM API for Processing XML with Java

[Wolfgang Hoschek <whoschek AT lbl.gov>]

Builder.setupParser() and knownGoodParser() do some checks for known 
parsers ala

if (parser.getClass().getName()) { ... special configure ...}

If the parser is a SAX XMLFilter then this would not really help, so 
the suggestions is to have the code in these methods check if the 
parser is an instanceof XMLFilter and walk the parser tree via 
getParent() until a parser is found that is not an instanceof 
XMLFilter.

[In practise, the case arises with BuilderFactory.getMSVBuilder which 
is implemented as an XMLFilter]
