 Throughout this API, multiple arguments and returns are labeled as an RSpec. These fields shall be understood as XML documents following one of the schemas advertised in the return from !GetVersion. All such RSpecs must pass an XML schema validator, must list all used schemas and namespaces within the document, using schemas that are publicly available. The !GetVersion return advertises schemas for advertisment and request RSpecs; the schemas for manifest RSpecs are assumed to be available at the same base URL, but using a corresponding manifest schema.
 
-A fully GENI AM API compliant aggregate will always support the GENI standard schemas for RSpecs, available at http://www.geni.net/resources/rspec. As of 4/2012, the current GENI RSpec version is '''3'''.
+A fully GENI AM API compliant aggregate will always support the GENI standard schemas for RSpecs, available at http://www.geni.net/resources/rspec. As of 4/2012, the current GENI RSpec version is '''3'''. Aggregates are free to use an alternate format internally, but must accept and produce compliant RSpecs on demand. 
+
+The Aggregate Manager API requires this contract: Aggregates advertise the `type` and `version` of RSpec formats that they support. If available, they specify the `schema`, `namespace` and `extensions` combination which is the authoritative definition of that format. Clients of the API should understand that combination in order to know how to understand the resources available at that aggregate.
+
+If an aggregate advertises a particular `type`/`version` (optionally defined with a combination of `schema`, `namespace` and `extensions`) in the `geni_ad_rspec_versions` attribute of !GetVersion, then it promises to send a correct Advertisement RSpec in response to a !ListResources call which supplies a `geni_rspec_version` option containing that `type`/`version`. (`geni_rspec_version` is a struct with 2 members, `type` and `version`. `type` and `version` are case-insensitive strings, matching those in `geni_ad_rspec_versions`).
+
+If an Aggregate advertises a particular `type`/`version` (optionally defined with a combination of `schema`, `namespace` and `extensions`) in the `geni_request_rspec_versions` attribute of !GetVersion then it promises to correctly honor a !CreateSliver call containing a request RSpec in the given format, and then to return a Manifest RSpec in the corresponding format (i.e. a GENI format request is answered with a GENI format manifest). The aggregate also promises to send a correctly formatted Manifest RSpec in response to a !ListResources call which supplies a valid `geni_slice_urn` option and an `geni_rspec_version` option containing that supported `type`/`version`.
 
 In this API, such RSpec fields are labeled as type `geni.rspec`.
