+metadata files. This does not verify for correctness, only that the required
+members exist within the file and are non-null. The required members are:
+  Name
+  Version
+  ServiceDirectory
+  SdkType
+  IsNewSdk
+For Java only
+  Group
+
+.PARAMETER DocRepoLocation
+Location of the documentation repo.
