Hi John and Curtis, You certainly can validate schemas with Xerces-j--personal.xsd included : -). But to do so you need an instance document which references the schema; when validating the instance document Xerces will simultaneously validate the corresponding schema.
Hopefully at some point Xerces will be able to validate a schema against te Schema for schemas, but we're not quite there yet. Building in functionality to validate schemas alone is very important--especially if we want to have grammar caching--and that's definitely on the agenda for Xerces2. But for the moment the best you can do is write a trivial instance document that references your schema and use that to call Xerces's schema validation capabilities; any help anyone can give to move things along would certainly be welcome!

Can i validate a schema? 2. if so, how do i validate it? against what? tnx! johnu On Mon, 14 May 2001, Ashish wrote: > try using > bash-2.03$ java dom/DOMCount -v -n -s > ~/xerces-1_3_1/data/personal-schema.xml > > > ----- Original Message ----- > From: "Curtis Brown" <[EMAIL PROTECTED]> > To: <[EMAIL PROTECTED]> > Sent: Monday, May 14, 2001 1:56 PM > Subject: personal.xsd example won't validate > > > > Using xerces 1.3.1, I try to run the DOMCount sample on the > > personal.xsd file from the data subdir, but I get the following > > errors: > > > > bash-2.03$ java dom/DOMCount -v -n -s ~/xerces-1_3_1/data/personal.xsd > > [Error] personal.xsd:2:53: General Schema Error: Grammar with uri 2: > http://www.w3.org/2000/10/XMLSchema , can not found. > > [Error] personal.xsd:2:53: Element type "schema" must be declared. > > [Error] personal.xsd:4:28: Element type "element" must be declared. > > ... > > > > Has anyone been able to validate personal.xsd?
