Creating metadata on 5.6

I've noticed that, on 5.6.4, creating metadata fails - the TypedValue is missing. XML shown by temporarily adding print_r($data) to the post function in ServiceAbstract.php.


    <MetadataEntry>
       <Domain visibility="PRIVATE">SYSTEM</Domain>
       <Key>test-key</Key>
       < xsi:type="MetadataStringValue">
           <Value>test-value</Value>
       </>
   </MetadataEntry>


Should be:


    <MetadataEntry>
       <Domain visibility="PRIVATE">SYSTEM</Domain>
       <Key>test-key</Key>
       <TypedValue xsi:type="MetadataStringValue">
           <Value>test-value</Value>
       </TypedValue>
   </MetadataEntry>
   
Error:
