If you had to manually select “All files” I suspect a version issue. Earlier versions of XMetaL don’t support rng, only xsd, rlx and rld.
Has anyone had success running the revised EAD in Xmetal? I was trying to play with it to find any discrepancies, but keep getting the same error message. I’m using the newest version (7.0).
1. Opened ead_revised_test_instance.xml
2. Using XMetal pop-up box, browsed for schema
3. Had to switch Files of type: box to "all files"
4. Selected ead_revised.rng
5. Got error message: "ead_revised_test_instance.xml" could not be loaded. XML schema namespace 'http://www.w3.org/2001/XMLSchema' is not declared"
