    A couple of notes on this one:
    
    1) Having had more time to reflect, I think there might be legitimate 
    instances of an <alert> of type Alert with no included <info>... 
    especially if the scope is Restricted or Private.  Anyway, making the 
    presence of an <info> block mandatory when the value of <msgType> is 
    "Alert" would complicate both the schema and any strict 
    implementation thereof.  So I'm thinking it might be more appropriate 
    to make this a SHOULD (or even a "normally SHOULD").
    
    2) It seems this could be expressed more simply in the affirmative by 
    saying something like: "Under most circumstances CAP messages with a 
    <msgType> value of "Alert" SHOULD include at least one <info> 
    element."
