Has anyone used the ConstraintRelationship class for Dynamics CRM?

As documented here there is a property on the AppointmentRequest class for the CRM webservice that allows you to add constraints to what possible appointments are returned from a search.

The actual constraint is specified as an xml string, but I can find almost 开发者_开发问答no documentation about it. Can any one point me to any relevant resources?

I was never able to find any quality documentation on this property or an accepted schema. About all that is available (that I've found) exists on this example from the SDK: Schedule A Resource

You can kind of see how you would limit the search results to a set of resources/users. The list of which properties can be replaced for "name" in the example is in the article ConstraintRelation.Constraints Property.

Hope this helps...
