Advertise counts of metadata in GetCapabilities XML, such as:

• number of services
• number of datasets
• number of harvested resources
• number of datasets from services (WMS layers, WFS feature types, SOS offerings, etc.)

...using the pycsw taxonomy (between type and schema, and source fields).

Example from CubeWerx:

<ows:ExtendedCapabilities>
 <ObjectCounts>
  <Count objectType="urn:cw:def:ebRIM-ObjectType:CubeWerx:WMS:Layer">74</Count>
  <Count objectType="urn:cw:def:ebRIM-ObjectType:CubeWerx:WFS:FeatureType">56</Count>
