I"ve looked through the Integration guide, but there's alot of gaps in the documentation. Is there a guide or DTD explaining what XML tags are recognized and possible values for them? Possibly some examples? I'd like to know more than just VPS's, but also plesk client, plesk domains, misc hosting plans, etc. A second thing that would be nice is documentation of all the perl objects (order, subscription, etc.) and how to process them. I guess a list of all the available objects and their properties would be a good start.
