[ZDP] Software Product on test site

[TFE MMS JARVIS JOHN]

I've been poking around the test site and tried out the Software
Product (among other things ;) I found that, within the software
product, Add HTML Document and STX Document lead me back to the login
screen and sometimes popup a login dialog.  Entering a password does
nothing but I don't get logged out, either so I can just go back to
wherever I was.

What do HTML Document and STX Document do?

Are these examples of ZClasses that I keep reading about?

This stuff is looking really great!

               somewhere to try out :^)
