Florent Guillaume commented on CMIS-655:
----------------------------------------

Al, what do you mean by "query only exposes the properties on the type and not on the sub-types". There's includedInSupertypeQuery for that, isn't it?

> Since folder getChildren is basically a specialized query against two different tables, supporting all orderBy values for all possible orderable properties becomes prohibitively difficult for some repositories.
> In some repositories, the underlying query against all documents (and sub classes of document) may not permit sorting by a field that only may be present on a subclass of document.     But the scope of this call implies all cmis:document subclasses and all cmis:folder subclasses. 
> An example of a case that may be difficult to correctly service is the following: 
> A subclass of cmis:document named invoicedoc exists that has a an orderable property value of 'foo'.
> A folder getchildren is then reqested for a folder with an orderBy parm set to "foo".
