I don't have this documentation, but I don't think I'm actually asking for anything
Lumenvox specific.  It's more about how the AGI protocol works.  Here's a bit of
my asterisk log while running the normal pizza demo:


     -- Executing Set("IAX2/66.225.202.80:4569-4", "TOPPING=<item index=0>
<toppinglist>
<item index=0>
<ingredient>
onions
</ingredient>

</item>
<item index=1>
<ingredient>
pepperoni
</ingredient>

</item>

</toppinglist>

</item>
") in new stack


So as you can see the demo is setting the value of an asterisk variable to a
value which spans lines (and happens to be an XML fragment, but I don't think you care
about that).  The problem appears when I try to call getFullVariable() on a
variable which returns such a multiline value - the current implementation
of AgiImpl only reads the first line which here is "TOPPING=<item index=0>
and doesn't follow through and read the rest of the lines up to the following
double quotes.  Now I'm sure there is some complication in the AGI protocol
as to how to handle escaped quotes (if they are allowed at all).

So I think the solution is to modify AgiImpl to read the full set of lines for a
response and not stop at one - up until it reads the close quote.  Then I
can simply get that multiline string to my java code, interpret the XML
as I see fit, and should be all set.

So multiline variable values has been a possibility all along, it's just never
been encountered before now.
