I am sure Hoff knows but just so that everyone gets it:
* REST style web services and RPC style web services are two
   different styles of API - REST style is based on CRUD of
   data - RPC style is mimicking method calls
* RESTful (REST style) web services are typical either
   JSON/HTTP(S) or XML/HTTP(S)
* today JSON/HTTP(S) is way more common than XML/HTTP(S)
   (more compact format)
* among those not familiar with the history of web services
   REST is sometimes used as synonym for JSON/HTTP(S) also
   if the service really is more RPC style

Yes.

The support both normal transactions and XA transactions.

Today message queues are part of most transaction processing
solutions.
