Answer 1

The value of controls are passed to the persistence layer REST API in an XML document, as the body of the HTTP request. So in crud.xpl (say the one for eXist), this will be a document under /request/body. The exact path depends on your section and control name. For instance, if the section is named address and the field city, the value will be under /request/body/form/address/city.
