Fix Version/s: Java-SDO-Next
> Add support for sdo:unset attribute in change summary [SDO-120]
> ---------------------------------------------------------------
>
> Key: TUSCANY-877
> URL: https://issues.apache.org/jira/browse/TUSCANY-877
> Project: Tuscany
> Issue Type: Improvement
> Components: C++ SDO
> Affects Versions: C++-SCA-Next
> Reporter: Geoff Winn
> Fix For: Java-SDO-Next
>
>
> Currently there is no way to distinguish an unset value from an unchanged
> value in the change summary.
> The solution is to add a new attribute, sdo:unset, which contains a space
> separated list of unset old property values.
> For example:
> <datagraph>
> <a>
> <val1>hello</val1>
> <val2>world</val2>
> </a>
> <changeSummary>
> <a sdo:ref="#datagraph/a sdo:unset="val2">
> <val1>guten tag</val1>
> </a>
> </changeSummary>
> </datagraph>
> This is a 2.1 specification change, identified as SDO-120 in the
> specification change list.
