Hi Florent, Try a system rewrite instead of an URI rewrite. Best Regards, George -- George Cristian Bina <oXygen/> XML Editor, Schema Editor and XSLT Editor/Debugger http://www.oxygenxml.com Florent Georges wrote:

Hi,

I use <?oxygen RNGSchema="http://.../d/...rnc" type="compact"?> to associate an RNG compact schema to an XML document. The schema is actually cached on my machine, and the relevant catalog is added to the catalog list in the oXygen options:

<rewriteURI uriStartString="http://.../d/" rewritePrefix="file:///Users/.../schemas/"/>

but if I cut the Internet wire, the validation fails because oXygen cannot access the schema over HTTP.

Are catalogs used to validate through this PI? If they are, did I make something wrong?
