Instead of adding methods to the SAX2 classes, have you considered using
the existing ones to pass additional elements/attributes from a specific
namespace to the applications using the existing ones ?

In this case, you would use instead a startElement with a namespaceURI
set to this namespace, a localName set to "attributeDecl" and attributes
containing the name, type, defValue and value.

The applications would then see this as an element:

<xxx:attributeDecl name="..." type="..." defValue="..." value="..."/>

The main benefit from this method is that the additional information
gathered from your documents are passed to the applications using a
common and "standard" API and that you don't need to modify the layer
between these applications and the SAX parser to get them.

For instance, you can directly apply a XSLT transformation on your
documents using this parser and access to the attribute declaration with

I have described a similar application in August last year:

Hope this helps.
