The use of external references (Xref and image–ref) provides a portion of advantages over the use of common blocks. However, there may be problems in connection with the audit management. All external references that are included in any revision must have thje same time stamp and come from the same time as the main file, which is the audit. Audit Volume takes care of this task, since the function is used to bind all files as blocks that are stored in the audit file.
Revision Bind takes care of this task, since the function is used to bind all files together as blocks that are stored in the audit file. Moreover revisions of image references are extracted so that the main file imagereference point to the correct revisions.
This causes that an earlier revision of a file always looks as it did when the audit was made.
The control is done without interrupting the connection with external references.
