Java module version 1.7

This feature is being filed as a response to a posting on NetBeans mailing 
lists - http://www.netbeans.org/servlets/ReadMsg?msgId=166043&listName=nbdev

My module recognizes certain .xml files as its own. These xml files could
have corresponding java/class files too. The module has to identify the 
java/class files as secondary entries, because it isn't mandatory that they 
exist for every xml file that is recognized by the module. 
I would like to be able to recognize java files as secondary, yet
leverage the java module code - so that the source editor, source node, bean
patterns etc show up as they do for a regular java file but as a part of my XML 
node.
Looking at the code for JavaDataObject, it appears as if the java module is 
quite tightly tied to a java source file being the primary file.

The workaround is to use a pointer to the JavaDataObject from my xmlDataObject. 
But this does not solve the problem because actions like Source Control 
checkouts that are performed should check out *both* files. The only way both 
files are treated as a single unit is by using a multidataobject that uses the 
xml as primary, and the java as secondary.

This capability is quite important to the application that we are developing. 

Thanks.
