Accepting Petri Nets

I apologise if it's a stupid question, but could someone tell me the difference between an Accepting Petri net and an ordinary Petri net?
Thanks!

    Hi,

    An accepting Petri net has an initial marking and a collection of final markings. An ordinary Petri net mayhave an initial marking but has no final markings. Because the accepting Petri net has final markings, we can check whether the Petri net accepts some trace: If it can reaches a final marking from the initial marking by executing that trace, it accepts the trace.

    Kind regards,
    Eric.
