1. A system for decomposing a set of schema files comprising: at least one processor configured to: automatically identify a plurality of root schema files in the set of schema files by making a list of all schema files in the set of schema files, and removing from the list each schema file included or imported by another schema file of the set of schema files, wherein each root schema file is limited to information for that root schema file; and create a subset for each identified root schema file, wherein each created subset contains the corresponding identified root schema file and at least one particular subset further includes one or more non-root schema files that indirectly provide information for a particular root schema file of the at least one particular subset.
