Default option for Result Content when the operation is discovery is missing in TS-0001 R3
In TS-0001 R3, Table 8.1.2-1: Summary of Result Content Values indicates the applicability of RCN values for different operations. All operations except Retrieve (filterUsage='discovery') have a default option, meaning this RCN should be applied when RCN is not provided explicitly.
At the same time, in TS-0004 R3, Table 7.5.2 2: Elements used for response content says that for the discovery operation when RCN is not provided m2m:URIList
with data type list of xs:anyURI
should be used (see 3rd row), so the default RCN should be applied. This is inconsistent with TS-0001 as the default RCN is not specified there.
This issue applies only to Release 3. In Release 4 and 5, a new RCN discovery-result-references is added which is the default option for Discovery operation.
