xch_cmd
This is an anchor field which indicates that the specified command should be
sent to the World (MUD, session, etc.) when the anchor is selected.
Examples:
In this example, the anchor text will be "Take a look at Jim", and when that
text is selected (clicked on, etc), the command "look Jim" will be sent to the
World:
Take a look at <a xch_cmd="look Jim">Jim</a>.
This example is similar, but uses xch_hint:
You can go <a xch_cmd="go north" xch_hint="Go North">North</a>.
