The only way that comes to mind is to issue a full GetFeature request.
If the server is generating the collection bounds (which are optional)
one can get away with just reading those, otherwise the full
response has to be scanned just to generate the bounds.
Un-advisable thought, the response can be as small as a few kilobytes,
or as big as many gigabytes (so the bounds computation using that
approach cannot be expected to use a reasonable time).
Moreover, the server can be configured to return a max amount of
features, less than the total available, which would result in
a faulty computation.
