I’m trying to set up BaseX to manage a repository of DITA content. The DITA content has been specialized to validate against Relax NG schemas instead of DTDs. While importing content that validate against DTDs is straight forward, I have not yet figured out the best way to import Relax NG based content. So, I have a few questions:

• I see there is the Validation module [1] and that’s good because I think XQuery is my best option for managing the imports. However, I need to pass a specific schema to the functions. DITA content utilizes multiple schemas. Is there some way I can pass a directory to these functions instead of just a single file reference?
• I currently have the CATFILE option set [2]. Does this help or hinder importing when choosing to validate against Relax NG? Is there some way I can set the global options to make validating against Relax NG easier?
• I’ve seen multiple examples of people actually storing the schema(s) in the database. Is that necessary or help for using the validation module?

Thanks for your help!
