When sequencing multiple ddl files in rapid succession, the sequencers may produce extra intermediate nodes that have different same-name-siblings. Example: /sequenced/ddl/ddl[2] and /sequenced/ddl[2]. This is appearing on ddl files but may be occurring on other type of files. Two ddl files attached. This may not be causing problems but certainly is extra baggage in ModeShape. Below is the query results showing the extra nodes:
