You can accomplish this with model groups. You can create one
model group to hold the "header" elements, and one to hold the "child"
elements (both must be declared globally). Within each model group, specify
the "choice" compositor to avoid having order enforced. For
example:
<xsd:group name="HeaderElementGroup">
<xsd:all>
<xsd:element
name="header1" type="[sometype]">
<xsd:element
name="header2" type="[sometype]">
<xsd:element
name="header2" type="[sometype]">
</xsd:all>
</xsd:group>
<xsd:group name="ChildElementGroup">
<xsd:all>
<xsd:element
name="child1" type="[sometype]">
<xsd:element
name="child2" type="[sometype]">
</xsd:all>
</xsd:group>
Then, define the "parent" element using the "sequence"
compositor and reference the two model groups within it:
<xsd:element name="parent">
<xsd:sequence>
<xsd:group
ref="HeaderElementGroup">
<xsd:group
ref="ChildElementGroup">
</xsd:sequence>
</xsd:element>

help in processing compositor's in XML Schema?
I am trying to define the following in a XML Schema. I would
like the
elements , header1, header2, and header3 to
be un-ordered within themselves
and child1 and child2
to be un-undered within themselves. but I would like
to define that the header's occur before the child's.
Without introducing more tags, Is there a way to do this
??
<parent>
<header1/>
<header2/>
<header3/>
<child1/>
<child2/>
</parent>
