Validating eaDocX documents with Model Expert
The contents of package-based sections in your document, if they are managed by a Model Expert Reference Model, can be checked against that Reference Model.
If the package is not managed, then you can still check the contents against a Reference Model by choosing one from the drop-down list.
The results column shows a happy, neutral or sad face, and clicking on this icon shows you the results of the check as a list of violations.
Just select Model Expert 
in the eaDocX menu and follow the instructions.
Note: If your document contains other section types, such as reports or a glossary of document information, Model Expert cannot check these kinds of sections, as they can’t have a Reference Model.
