Meaning of "Is closed" attribute?

Hi,

this attribute comes from the BPMN Spec, which says:

"A boolean value specifying whether interactions, such as sending and

receiving Messages and Events, not modeled in the Process can

occur when the Process is executed or performed. If the value is true,

they MAY NOT occur. If the value is false, they MAY occur"

"There are two ways to specify whether unmodeled Activities are allowed to occur in Process instances:

• If the isClosed attribute of a Process has a value of false or no value, then interactions, such as sending and receiving Messages and Events, MAY occur in an instance without additional flow elements in the Process. Unmodeled interactions can still be restricted on particular Sequence Flow in the Process (see next bullet). If the isClosed attribute of a Process has a value of true, then interactions, such as sending and receiving Messages and Events, MAY NOT occur without additional flow elements in the Process. This restriction overrides any unmodeled interactions allowed by Sequence Flows in the next bullet.

• ..."

Probably you can find more information about that inside the spec.

Thanks a lot Sascha! I will consider the BPMN Specification in future before posting!
