Use XML messages for input and output. This option must be used for nested parameters
more than two levels deep.
Outgoing data
If the Web Service you are invoking requires input, the required fields are displayed
in a "template" format in the Outgoing Message. Edit the message, substituting a data
field of the appropriate type where indicated by the format
+_datatype. For array fields, you can add more lines, as necessary.
All fields in the outgoing message must be strings, so you must convert other types,
such as float or integer, to strings. For example, to use data field MyFloatData, you can
use convert(MyFloatData, string) in the message. This restriction applies only when the
message type is XML; in the Parameter format, Process Designer handles data conversions
for the messages.
Incoming data
For Incoming XML Data Field, specify a previously defined XML data field. You can use
one of the XPath functions in subsequent steps to extract the appropriate data from the
XML message.
