first of all: What is the best forum for issues with the production IDEA not the EAP?
My problem is that all xml:id attributes in my DocBook 5.0 files are red. I use DocBook 5.0 with XSD. I linked the docbook.xsd to the http://docbook.org/ns/docbook namespace in the resources settings. In the same directory as the docbook.xsd is, I have the DocBook shipping xlink.xsd and xml.xsd. IDEA uses its own xml.xsd from lib/resources.jar!/standardSchemas/xml.xsd. This xml.xsd file does not contain the xml:id attribute. So it is displayed red.
1. Why is the xml:id attribute missing in the IDEA shipping xml.xsd
2. Why does IDEA use its own xml.xsd if the import from docbook.xsd says: <xs:import namespace="http://www.w3.org/XML/1998/namespace" schemaLocation="xml.xsd"/> and I have the xml.xsd in the same directory.
