Returns the children of a remote document. Children of a
remote document are remote documents itself. This makes sense
if a database query has to be narrowed and is explained in
Hyperwave Programmers' Guide. If the number of children is 1
the function will return the document itself formated by the
Hyperwave Gateway Interface (HGI). If the number of children
is greater than 1 it will return an array of object record
with each maybe the input value for another call to hw_getremotechildren(). Those object records
are virtual and do not exist in the Hyperwave server,
therefore they do not have a valid object ID. How exactely
such an object record looks like is up to the HGI. If you
want to use this function you should be very familiar with
HGIs. You should also consider to use PHP instead of
Hyperwave to access external sources. Adding database support
by a Hyperwave gateway should be more difficult than doing it
in PHP.
