I guess it's the best way  - to extend but not to rewrite.

Strong   assertion.
Do you really have  example of capture file which breaks acse/pres 
dissectors?
If yes do you mind to send me such file(s) ?
I guess all what we need is to path acse/pres dissectors if need be using 
such capture file.
I already have MMS capture file you've sent me couple of months ago  - seems 
ok with acse/pres dissectors.
Thank you.
