Will xerces-j-2 support DOM revalidation and post schema validation info?
Dear Xerces2 developers,
I have few questions about Xerces-J 2's capabilities, hopefully you can
answer them in this early stage.
1. Will Xerces 2 support DOM revalidation? With this I mean the following:
An XML document is read in to a DOM. In this initial stage it is either
validated with schema or not. Then the DOM is modified. Will I be able to
re-validate some parts (e.g. a node) of the DOM without serializing the
whole tree as I have to do with Xerces 1.
2. Will I be able to access the schema post validation infoset? Some
explanation:
Can a ask about a single DOM node's datatype after it has been validated
with schema? Do I know whether a certain attribute comes from schema
defaults or not. What about the value of 'maxOccurs' facet and other facets?
Regards,
Mikko Honkala

Hi,

We are definitely considering and looking into it.
One of our priorities is to introduce XML Schema support into Xerces 2.
Doing that we will need to revisit current validation mechanism, as well
as consider re-validation of DOM tree in memory.

Hi Mikko,
I am also very intrest in this point, especially
revalidation against a DTD. If you get any information
please let me know!
Thanks a lot!
Annie.
