When we open process settings of a business process there is no process description that can be read there (please see screenshots http://prntscr.com/nb41yp, http://prntscr.com/nb4238, http://prntscr.com/nb426p, http://prntscr.com/nb42ar). Also if we take a look at the VwProcessLib table in database (that is responsible for information on business processes in Process library) there is also no process description field.
Unfortunately the value of this field is stored in SysSchema table and there is no way to connect to this table using filtering tool when selecting fields to display in Process Library since the table that stores information on business processes, as I mentioned before, is VwProcessLib. I will create a request to our R&D team so they could make this field accessible from Process Library. Thank you for helping us to make our application better!
I have another web service link which required output is in XML format. I'm not sure if its configurable in Process library or it will be only possible through code customization.
Below is screenshot of specific area of output from that web service link
