Michael, Thanks for the input, I hope someone else out there has some more insight. The problem I am running into is that different parsers deal with this differently. Which on is right?
XML Spy Version 5 rel 2 validates the given example with no problems. It seems as though XML Spy thinks that the XSD should be relative to the resource (xml file) not the other schema: <lom xmlns = "http://ltsc.ieee.org/xsd/LOM"; xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation = "http://ltsc.ieee.org/xsd/LOM lom.xsd http://ltsc.ieee.org/xsd/LOM/custom vocab/ext_vocab.xsd"> So again, two highly qualified XML parsers producing different results. What is the right answer?

In that last discussion I argued that relative URIs in the schemaLocation hints are relative to the resource in which they're actually dereferenced. Now I'm not so sure. You could argue that they're relative to the document entity or some base URI you've specified using xml:base. There doesn't seem to be anything in the spec [2] on how a schema processor should resolve realtive URIs specified in the schemaLocation hints. I'm sure someone else on the list could provide more insight.
