Had to put the Attribute, URL back into the Abstract so that Module Editor would compile. Leaving it out, and removing the AbstractURL elements from the MsaHeader.java and MsaLibHeader.java files cause even more problems.

When we can figure out how to remove them from the ModuleEditor, we can remove them from the Schema.
