We are trying to build a workbench which can work offline if it needs to, but can't find a way to supply it with the .xsd schema files at run-time.

We already have the .xsd files (the data is from the Ordnance Survey, and they gave us the files) but haven't been able to find a good way to provide them to the workbench - It looks like the only way is to open the workbench file in a text editor and edit the XSD_DOC and SKIP_SCHEMA_LOCATION_IN_DATASET values.

Is there a way to tell the workbench to (optionally) look in a specified location for the schema?
