[Arin-whoisrws] How to modify POCs?

[Ted Mittelstaedt]

I have looked through the data at

https://www.arin.net/resources/whoisrws/whois_api.html

but I am having trouble understading how to use the
interface to upload data to WHOIS-RWS

Obtaining a POC seems easy enough with the command example:

xsltproc poc.xsl http://whois.arin.net/rest/poc/KOSTE-ARIN

but there seems to me no example on how a remote host can
push a SWIP to WHOIS-RWS using the interface, or am I missing
something?

(Yes I know there's a human-friendly webinterface but thats
not what I'm looking for)
