SetServiceData example - Delete
A setServiceData operation with the following argument:
<ogsi:deleteByServiceDataNames>
   <name>tns:sd1</name>
   <name>tns:sd2</name>
</ogsi:queryByServiceDataNames>
Result is dependent on the mutability of the SDE
“static” and “constant” and “extendable” cannot be deleted
“mutable” results in deletion of all values of that SDE
Cardinality rules must be obeyed
For those SDEs that (for whatever reason) fail to be deleted
Their values appear in the result output
