Hi Jing, Your schema is definately invalid. Looks like your DTD 2 XML Schema conversion didn't happen cleanly. You have some pretty strange attribute references, such as "xmlns:go", and "xmlns:rdf". Instead of attribute references, those need to be changed to namespace declarations. You'll need to clean that up a bit.
For example: <xs:attribute ref="xmlns:go" fixed="http://www.geneontology.org/dtds/go.dtd#"; /> Move the "xmlns:go" to the root <schema> element as such: <schema xmlns:go="http://www.geneontology.org/dtds/go.dtd#"; ...> The same needs to be done for the xmlns:rdf. Also you'll need to import the "rdf" schema, if you are going to be making references to it's datatypes and element definitions. So you'll need to hunt down a copy of that schema, and then use an appropriate import statement. --Keith [EMAIL PROTECTED] wrote: > > Thanks for the reply, Keith.
