Prov-WD: Several Agents may have the same role

[Ole Streicher]

Hi again,

the description of agents says (pg. 19):

"There can be more than one agent for each activity with a different
role and one agent can be responsible for more than one activity or
entity [...]"

This implies that if there is more than one agent given, they shall have
different roles. This implication is wrong, and I would recommend to
remove the "... with different roles" part. Patch attached.

One example could be that several (independent) Agents have the role
"Funder" for an Activity, if the Activity got financial support from ore
than one organization.

Best

Ole
