_HIDDEN does not provide an alternative to virtual desktops, it merely allows 
WM to state in no uncertain way, that , for example, icon should not be shown 
on the Pager.

What is related to virtual desktop, is the paragraph that explains what Pager 
should/should not show when client is in particular state, depending on the 
mapping of client windows. I'd say that should be added to Pager 
Implementation Notes : 

<quote>
Pagers should follow the following rules while determining the way to 
represent client window : 
1) If either _NET_WM_STATE_SKIP_PAGER or _NET_WM_STATE_HIDDEN are set on the 
client, then Pager should not show this client.
2) Failing that, if client is in NormalState - Pager should represent 
client's main window.
3) If client is in IconicState and both its icon window and main window are 
unmapped then Pager should still represent client's main window
4) If client is in IconicState and its icon window is mapped (window id 
specified in WM_STATE property) - Pager should represent client's icon window.
