### 13.16.6 Eliminating duplicate ObjectIDs

If a file in your output contains duplicate FrameMaker ObjectIDs (see §5.3 Identifying files and objects), you get a W3C validation error. FrameMaker can get away with duplicate ObjectIDs because in addition to the number, references to objects include the format name and the entire text of the paragraph in question.

You must hunt down duplicate objects in your FrameMaker document, using clues from the validator error report and source listing. Remove one of the duplicate objects, then reinsert that object to make FrameMaker assign a new ObjectID. See §5.3.2 Working with FrameMaker ObjectIDs.
