I have a custom reference pointing to an
XmlTag inside of a XML file, for example
content.xml. When I try a rename or find usages on the referenced
XmlTag it’s not working. When I debug, the reference's
isReferenceTo() method is called with a
XmlElementDecl instead of the expected
XmlElementDecl has the same name as the XML tag and is in a
content.xml.dtd file, which only exists in memory (it’s not created by me and the XML file has no DTD).
How can I achieve that the rename and find usages is attempted on the actual
XmlTag instead of on a pseudo DTD element?
