CML Documentation? E.G. how to add Aspect to existing node?

Is there an update on availability of CML documentation?For example, I downloaded the 1.3 community SDK and tried to mod the Query1 to add an aspect to an *existing* node, but I can't get it to work (creating a node and adding an aspect in the same CML block with a "local id" of "1" works).Here is t

Try modifying the code to …


   …

    // Get the reference of the first result
   Reference reference = rows[0].getNode().getReference();

   // Setting a property
   NamedValue[] specificationProps = new NamedValue[1];

   // Is it possible to not set at all and still add aspect?
   specificationProps[0] = Utils.createNamedValue(PROP_MYPROP,"DDD");

   CMLAddAspect addAspect = new CMLAddAspect(ASPECT_MYASPECT,    specificationProps, new Predicate(new Reference[]{reference}, null, null), "1"); 

   …
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Basically the last parameter of the CMLAddAspect constructor is an id used internally to the CML statements, not a reference to an exisiting node.

As a note, the predicate could be build up to contain the list of all the References returned to from the query. Then you'll only need to make one update call. This means that the work will be done in a single transaction and with one payload sent and recieved from the server.

Hope this helps,
