I am afraid I don't understand where proprietary feature comes in, nor the need for subclassing.
Lets say I have an off-the-shelf parser (AElfred?) and an off-the-shelf DOM (Docuverse?).
I'm writing a program that needs to use the DOM to process documents that use namespaces.
So I wrap John Cowan's inheritance filter around the parser and feed the filter to the DOM.
Then I write a static methods for fetching a qualified name from an element...
public static String getQualified(Element);
My application then uses this 5-line method to access the qualified names when it needs them.
I then manipulate the tree as needed. When done, I walk the tree, generating SAX events,
feed them through an uninherit filter, and compose a document from the result.
Yes, my application is proprietary. It should be!
But the interfaces are conformant. And the components are all conformant. And it was
pretty easy to use all this conformant software to put together an application which
pushes a document which uses namespaces through the DOM.
Isn't this the real strength of standards? Being able to get off-the-shelf software from
multiple vendors, integrate them into an application, and do something real???
I really don't understand your comment.
