No, that's not the goal of this utility. The DOM object in XSSerializer is just an intermediate representation of the input Schema, which we serialize to lexical XSD syntax (which we see in a text editor for example). Producing the lexical XSD syntax as output, is the actual goal of this utility. But interestingly, looking at a DOM model of XSModel is also a useful representation, to look at I guess. > what does the term "lexical, XSD syntax" means in "XSModel serialization > utility. * I've explained this above. > I'm trying to implement SCD support for Xerces.

After having a quick look at SCD spec, I guess implementation of SCD would require following implementations: 1. Parser & evaluator for SCD syntax (ref, http://www.w3.org/TR/xmlschema-ref/#section-scd-syntax). 2. Parser & evaluator for Schema Component path syntax (ref, http://www.w3.org/TR/xmlschema-ref/#section-path-syntax). The evaluation of SCD paths, could return references to Schema components (from the input schema document). The SCD path expressions would operate on some in-memory representation of input Schema. Quickly, I could suggest following implementation strategies for Xerces SCD implementation: 1. The first implementation variant, could take XSModel as input, and return say a list of XSModel schema objects, after evaluation of the SCD path expression. 2. The second variant, could take Schema DOM as input (which you could re-use from the XSSerializer utility, that i've written), and return a list of Schema DOM nodes, after evaluation of the SCD path expression. > Also, Is there a similar implementation for SAX as well? I don't think, this exists at present. But I guess, an implementation of this could be possible. Probably, somebody could add more to this discussion. -- Regards, Mukul Gandhi --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
