Hi Mohamed,
The format may depend on the intended FS Standard to be audited but typically this only specifies the information required to be included, eg Rev.No. so the exact format is up-to-you.
There is a near- infinite variety of HACCP Plan presentations within a basic Codex-like structure in use which may dictate the preferred format style but IMEX the choice is often related to things like (a) the documentation system, eg whether various manuals A,B,C etc are used, (b) the style preferred by author for making revisions in the documents, eg re-issuing the whole manual for every change, only re-issuing the chapter/section/page etc etc, (c) the method of approving documents before issuance, and so on. 
IMO the simplest approach is to keep re-issuing the whole manual after a change if you have loads of processing power and it's not encyclopedic in size. This allows easy use of Issue numbers. Unfortunately i didn't have that luxury and i found the alternatives can get quite tiring in complexity. It may be different if you have a nice "Documentation team" to pass the buck onto.
It can also be useful to imagine that you are an auditor and need to be able to move smoothly through the manual in respect to the auditable clauses in the related FS Standard (if any). Any excessive freakiness of documentation style can get rapidly confusing/irritating.
PS - with reference to previous post, i used Ver. for BRC because i had already used Issue in the HACCP manual.
But it's ultimately up-to-you/your system of course
