MetadataURL links are not followed for FeatureTypes in WFS or Coverages in WCS

[rmcaleer]

Steps to reproduce: * Go to 'Administration->Harvesting Management' in Geonetwork * Add an OGC Web Service ** Select one of the WFS or WCS options ** Select 'Create metadata for layer elements using MetadataURL attributes (if existing, if not use GetCapabilities).' for the 'Type of Import' * Go back to the Harvesting Management page, select the added OGC Service and 'Run' it to start harvesting.

There's no easy way to tell if it follows the MetadataURL links. I set up a remote debug session to my Geonetwork install from eclipse and put a breakpoint in the org.fao.geonet.kernel.harvest.harvester.ogcwxs.Harvester class in the addLayerMetadata method. On line 505 there is the following check:

if (params.useLayerMd && params.ogctype.substring(0,3).equals("WMS")) { ...

The code within this if block does the parsing of the MetadataURL element, but unless it's a WMS this section is never called and there is no other code to parse MetadataURL elements if it's a WCS or WFS.

* Note: Filing as a defect (rather than enhancement) since I haven't found anywhere in the app or documentation that suggests MetadataURLs aren't supported for WFS & WCS (so the implication is that they are).
