There is a problem to get these
   <sequence minOccurs="0" maxOccurs="unbounded">
   <choice minOccurs="0" maxOccurs="unbounded">
   etc

in a Perl nested datastructure.  Therefore, these get a label
which is the first element of the sequence/choice prepended by
seq_ resp cho_.

For instance, as schema:

   <element name="a">
   <choice maxOccurs="5">
     <element name="b">
     <element name="c">
   </choice>
   <element name="d">

An instance in Perl

   { a => 1
   , cho_b => [ { c => 3 }, { b => 2}, { c => 42} ]
   , d => 13
   };

When maxOccurs <= 1, there is no need for such prefix or complexity.
