In my schema definition, I have certain element that are used
commonly in most of the place. 

For e.g

	<xsd:complexType name="TitleStructure" mixed="true">
		<xsd:choice minOccurs="0" maxOccurs="unbounded">
			<xsd:element ref="sub"/>
			<xsd:element ref="sup"/>
			<xsd:element ref="u"/>
			<xsd:element ref="i"/>
			<xsd:element ref="b"/>
			<xsd:element ref="a"/>
			<xsd:element ref="smallcaps"/>
		</xsd:choice>
	</xsd:complexType>


	<xsd:complexType name="ParagraphStructure" mixed="true">
		<xsd:choice minOccurs="0" maxOccurs="unbounded">
			<xsd:element name="FootNote" type="FootNoteStructure"/>
			<xsd:element name="AuthorComment" type="xsd:string"/>
			...
			...
			<xsd:element name="InlineFigure" type="InlineFigureStructure"/>
			<xsd:element ref="b"/>
			<xsd:element ref="i"/>
			<xsd:element ref="u"/>
			<xsd:element ref="sup"/>
			<xsd:element ref="sub"/>
			<xsd:element ref="a"/>
			<xsd:element ref="smallcaps"/>
		</xsd:choice>
	</xsd:complexType>

where you can see Iam refering "b", "i" etc in both TitleStructure,
ParagraphStructure. So, i prefer instead of refering everytime these
b, i, sup etc, can i put them as a group under some name and ref that
group

i.e something like

<suitable xsd tag>
	<xsd:element ref="b"/>
	<xsd:element ref="i"/>
	...
	<xsd:element ref="smallcaps"/>
</suitable xsl tag>

and then refering this in
	<xsd:complexType name="TitleStructure" mixed="true">
		<xsd:choice minOccurs="0" maxOccurs="unbounded">
			<refering that pre-defined tag/> -- THIS WAY
		</xsd:choice>
	</xsd:complexType>

I did look for similar thing in xsd, but could not find a answer. But
i believe there is an xsd answer. Anyone can you pls suggest the
pretty way.

Thanks
karl
