[Talk-GB] Disconnecting a way that's connected to a relation

[Mark Goodge]

There's a park near me that I want to fix some of the boundaries of, and 
in one place that means disconnecting the way which forms the park from 
an adjacent way which forms a highway. But, in ID, I can't do that, 
because I get the message "This can't be disconnected because it 
connects members of a relation".

However, the way I want to move isn't part of a relation - it's only the 
way which forms the highway which is.

Is there any easy way, in ID, to disconnect a way from others while 
leaving the rest connected?

In this particular case I'm thinking it might just be simpler to delete 
the entire park and re-add a new area for it with the boundaries in the 
right place, but that seems a bit overkill.

Any suggestions?
