xml-dev - Re: SAX2: Namespace Processing and NSUtils helper class

[Ray Waldin <rwaldin@pacbell.net>]

I'm only a user of SAX and not an implementor, but I've always expected SAX 2 to include
namespace scoping events.  It seems a bit restrictive to completely hide these events from
an application.  For example:

<element1 xmlns="uri1" xmlns:p2="uri2">
  <ns2:element2 foo="bar" xmlns:p3="uri3" p3:whiz="bang"/>
</element1>

would produce the following stream of events:

  startDocument();
  startNamespace( prefix=null, uri="uri1" );
  startNamespace( prefix="p2", uri="uri2" );
  startElement( name="element1", attrList=null );
  startNamespace( prefix="p3", uri="uri3" );
  startElement( name="p2:element2", attrList={ foo="bar", p3:whiz="bang" });
  endElement( name="p2:element2" )
  endNamespace( prefix="p3" );
  endElement( name="element1" );
  endNamespace( prefix="p2" );
  endNamespace( prefix="p1" );
  endDocument();

Simple management of these namespaces can be provided for in some helper class like the
NSUtils example, and can even be handled automatically for the most part in a new
HandlerBase2 class, but this decision of how (or whether) to handle namespaces could be
left to the application author.  Anyone else feel this way?
