having problems using the all compositor

[Bill Riegel <BRiegel@lgc.com>]

Structure

<Table>
  <attribute1>name</attribute1>
  <attribute2>5</attribute2>
  <out_of_hierarchy_table1>
    <attribute1>red</attribute1>
  </out_of_hierarchy_table1>
  <out_of_hierarchy_table2>
    <attribute1>green</attribute1>
  </out_of_hierarchy_table2>
  <child_table1>
    <attribute1>cow</attribute1>
  </child_table1>
  <child_table2>
    <attribute1>horse</attribute1>
  </child_table2>
</Table>

Desire:
	What to have an order that dictates:
	Table's attributes occurs first
	Out_of_hiearchy_tables occur second
	Child_tables occur last.

	But with each group allow an un-order list.
	i.e. allow attribute2 before attribute1
	     allow out_of_hiearchy_table2 before out_of_hierarchy_table1
	     allow child_table2 before child_table1

I get the following error output:

Table.xml:3:Error:  cos-all-limited.1.2: A group whose content is "all" must
only appear as the content type of a complex type definition.  Saw group in
"sequence".
Table.xml:3:Error:  cos-all-limited.1.2: A group whose content is "all" must

"sequence".
Table.xml:24:The content of element type "Table" must match "EMPTY".

Is there another way to achieve my desired goals ?

Note: XMLSpy is happy with the above XMLSchema.
