[OWSLib-users] CSW BBox constraint

[Thomas Kræmer]

Thank you for the link, Rich.
As far as I understand the linked discussion different servers handle the
bounding box filter differently.
I believe the server I'm working with is an ERDAS Apollo server.
Based on your link I've now tried the following two versions, but I am
still getting no results back:
