hw_getremotechildren - Gets children of remote document

SYNOPSIS
       mixed hw_getremotechildren (int	$connection, string  $object_record)

DESCRIPTION
	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 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.

PARAMETERS
	      o $connection
		- The connection identifier.

	      o $object_record
		- The object record.

RETURN VALUES
	If  the  number  of  children is 1 the function will return the document itself formatted 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(3).  Those	object	records  are  virtual and do not exist in the Hyperwave server, therefore they do not have a valid
       object ID. How exactly such an object record looks like is up to the HGI.
