Allow the known subelements to also be root in ALL files
Sometimes you just want to write a part of the ALL file ... like for a template. In such a case it would be nice if the sub-elements of an ALL file like BUSINESS PROCESS LIBRARY or CLASS or RELATIONCLASS etc. could be the root and highlighted properly.
Filing it as a bug cause it also isn't properly indicating the code as "false", but I think the above description is a better solution. We should be allowed to expect the user to have some knowledge about ALL.
