I’m trying to connect with the ImageServer API. I’ve established a socket connection and now I want to invoke `connect. In the docs, I see this example XML request body:
```
<?xml version="1.0" encoding="UTF-8"?>1
connect
dummy
dummy
[guid]
id=[guid]&connectiontoken=[token]
```
Here as well as all subsequent examples that mention the element, does not explain its properties aside from that it needs to be a number. Should it be unique? Maximum number? Can it be negative?
