CEA and UWS-PA standardization

I have read the Note on the relationship between these Standards/ Implementations and I wanted to point out the work that has already been done in moving CEA towards standardization - I will try to relate the content of these drafts to the content of the UWSCEANOTE http://www.ivoa.net/Documents/cover/
IntroductionCEA_UWS-20071005.html using the nomenclature of the note and to the latest UWS specification draft http://www.ivoa.net/ internal/IVOA/IvoaGridAndWebServices/UWS-0.3.pdf. To be concrete lets look in terms of the current drafts that I published for Beijing to the IVOA wiki http://www.ivoa.net/twiki/bin/view/IVOA/ CommonExecutionArchitecture, which actually are links to my ESO home web.

1. CEAApplication http://www.eso.org/~pharriso/ivoa/ CEAApplicationDM.html This describes the schema that is the basis of both the registration of and the JDL for the UWS-PA. The document talks about CEA v1 because this would be first version that was published under an IVOA controlled namespace, however in terms of [UWSCEANOTE] this is CEAv2 and perhaps the document and schema should carry this numbering.
2. CEAInterface http://www.eso.org/~pharriso/ivoa/CEAInterface.html This contains a first iteration at defining both changes to the CEC interface to add some concepts back from UWS as well as a first attempt at formally specifying UWS-PA in WSDL 2 with accompanying schema.

My remaining questions (not clear to me from reading [UWSCEANOTE]) are 1. is UWS still to have a SOAP profile - if so will this effectively be CEC1 - or CEC2 (which is an update on CEC1 to conform with the UWS pattern described in UWSDOC)?
2. is CEAv2 to be the only JDL for UWS-PA, or are others possible....

Cheers,

        Paul.
