[Paraview] removing domain constraints

[Utkarsh Ayachit]

Stephane,

Unfortunately such more involved control for inheritance is not
provided by ParaView, hence you'll have to go with copying the xml and
changing it. The base_proxy mechanism is very simple (to say the
least), it does not support overriding anything (including
properties/domains) defined by the base _proxy.
