Hello, i am creating a two file editors plugin. First editor is implicit, and second is my graphic designer. This first editor is asiciated with .jsl files, which basically contains content of standard XML Job Definition File for Batch Processing. What i want to do is to use standard syntax highlighting, code-completion and refactoring, which is standardly provided for XML files with this namespace "http://xmlns.jcp.org/xml/ns/javaee" but in addition i need to add an extra ID attribute for one of elements. Is there a simple way how to do it please?
