TS-0004: Remove default for timeWindowType of <crossResourceSubscription>
The attribute timeWindowType has a cardinality of 1 (ie it cannot be deleted) and is also mandatory in the CREATE request. This means that it is not necessary to have a default value defined in TS-0004's Table 7.4.58.13: "Resource Specific Attributes of <crossResourceSubscription> resource".
Proposal
Remove the default value for timeWindowType from table 7.4.58.13 in TS-0004.
