Subject: Re: Replace SchemaUtils/DOM with JaxMe's Schema Parser?

Hi Dims and all,
We went through your mail.
We want some clarifications on it.

1)Do we need to take the DOM node and use DOM2SAX for generating events?

2) Then if it is the case, where should we do that? Do it while in the
parsing at the SymbolTable or inside the SchemaUtls?

What we prefer is, keep the SymbotTable as it is and change it inside the
SchemaUtils, though it is a temporary solution.(Hope JAXMe people will come
up with a solution with accepting the DOM node).

So the changes only will be inside the SchemaUtils..............
Is this approach ok for doing it?
Kindly need your suggestions to move on.

Regards,
Jeyakumaran
