Hi Avin, > Actually I want to write following value: > <size><medium/></size> > or > <size><large/></size> > or > <size><small/></size> > or > <size>15</size> > > So value would be integer value or empty elements: <large/>, > <medium/>, <small/> That's impossible in W3C XML Schema unless you introduce xsi:type attributes to indicate the kind of <size> element that's being used. Would you be happy with: <size>medium</size> or <size>large</size> or <size>small</size> or <size>15</size> This would be easy to do using a union type: <xs:element name="size"> <xs:simpleType> <xs:union memberTypes="xs:integer"> <xs:simpleType> <xs:enumeration value="large" /> <xs:enumeration value="medium" /> <xs:enumeration value="small" /> </xs:simpleType> </xs:union> </xs:simpleType> </xs:element> Cheers, Jeni P.S. It's simple in RELAX NG: <element name="size"> <choice> <element name="medium"> <empty /> </element> <element name="large"> <empty /> </element> <element name="small"> <empty /> </element> <data type="integer" /> </choice> </element> --- Jeni Tennison http://www.jenitennison.com/
