9. The method of claim 8 , further comprising: in the event multiple OLE objects having different document types are discovered in the documents: copying OLE objects of a first document type from the documents to a documents of a type corresponding to the first document type to create first type discovered object comparison documents; copying OLE objects of a second document type from the documents to a documents of a type corresponding to the second document type to create second type discovered object comparison documents; comparing the first type discovered object comparison documents with a comparison engine that corresponds to the first document type; inserting a result of the comparing of the first type discovered object comparison documents into the comparison output document; comparing the second type discovered object comparison documents with a comparison engine that corresponds to the second document type; and inserting a result of the comparing of the second type discovered object comparison documents into the comparison output document.
8. A method of comparing documents, comprising: determining that a first document comprising a first primary document contains an OLE object; marking a first location of the OLE object; copying the OLE object to a document of a type corresponding to a document type of the OLE object, creating a first discovered object comparison document; determining that a second document comprising a second primary document contains a corresponding OLE object having the document type of the first OLE object; marking a second location of the corresponding OLE object; copying the corresponding OLE object to a second discovered object comparison document; comparing the first primary document with the second primary document using a comparison engine that corresponds to a document type of the primary documents, generating a comparison output document from the results of the comparing; comparing the first discovered object comparison document with the second discovered object comparison document using a comparison engine that corresponds to the document type of the OLE object; inserting a result of the comparing of the first discovered object comparison document and the second discovered object comparison document in the comparison output document according to at least one of the first location and the second location; and displaying the result of the comparing using a format that draws attention to differences.
