vcdxbuild is requiring a specific ordering of the
default and return elements within a selection element.

If I put the default before the return I get a parse
error:

xmas.xml:1160: validity error: Element selection
content doesn't follow the Dtd
Expecting (bsn? , prev? , next? , return? , (multi-
default | default)? , timeout
? , wait? , loop? , play-item? , select*), got (bsn
prev next default return tim
eout wait loop play-item select select select select
select select select select
 select select select select select select select
select select select)
    </selection>
               ^

But if I put the return before the default it parses
fine.

Note this is for version 0.7.11.

And on a side note the command line usage and help do
not show that you have to specify the xml file as an
argument on the command line:

C:\XMas>vcdxbuild --usage
