Opposite[edit]

I do not know how to mention it, but this property seems to be the opposite of destination point (P1444).

Use on 'trek' violating constraint[edit]

Revision 631398949 added a constraint check enforcing the property to only be used on occurrences. This seems to go counter to the description describing it as the "starting place of this journey, flight, voyage, trek [...]", so items not necessarily associated with a temporal entity. This causes e.g. a hiking trail to be marked as possibly problematic. Is this intended behavior?
