Hi Philippe,

Thank you for your review comments, Please find some responses below:

We did consider this and decided it is outside the scope of the 
vocabulary but of a higher-level model. For example, in EARL we have an 
HTTPContent class which in the current proposal contains exactly one 
Request and one Response class so that it represent exactly one 
client-server interaction.

Other options include using the RDF sequence lists (rdf:seq) which 
define a specific order of the list items. Each item in the sequence 
list could be a Request or Response. In other words, you will have to 
define the model for how to use this vocabulary in WSDL.

Indeed it is but the XML Literal needs to be converted to base64 first. 
It will also need to be translated back in order to be human readable...

Thanks for spotting these, not sure if we can slip in these changes 
before the publication.
