taken from the request and sent to the field's mutator.
Reference fields may have their target value(s) specified with a
delimited string query syntax, containing the portal_catalog search:
<FieldName>=index1:value1|index2:value2
eg to set the Client of a batch:
...@@API/update?obj_path=<path>...
...&Client=title:<client_title>&...
And, to set a multi-valued reference, these both work:
...@@API/update?obj_path=<path>...
...&InheritedObjects:list=title:AR1...
...&InheritedObjects:list=title:AR2...
...@@API/update?obj_path=<path>...
...&InheritedObjects[]=title:AR1...
...&InheritedObjects[]=title:AR2...
The Analysis_Specification parameter is special, it mimics
the format of the python dictionaries, and only service Keyword
can be used to reference services. Even if the keyword is not
actively required, it must be supplied:
<service_keyword>:min:max:error tolerance

an error; setting an empty value should clear the field
