(f1 | f2 | f3 )* is exactly what i was looking for. thanks for the responses. i need help for one more issue. i have a situation where i would like to have something like (f1?, f2?, f3*, f4+) one way to do this will be <xs:sequence> <element ref = "f1" minOccurs = "1" maxOccurs = "1"> <element ref = "f2" minOccurs = "1" maxOccurs = "1"> <element ref = "f3" minOccurs = "1" maxOccurs = "unbounded"> <element ref = "f4" minOccurs = "0" maxOccurs = "unbounded"> </xs:sequence> but this imposes a sequence and requires the fields to be ordered from f1 through f4. how can i get around this? thanks again. mohan >From: noah_mendelsohn@us.ibm.com >To: Anli Shundi <ashundi@tibco.com> >CC: Mohan Raj <mohanrajd@hotmail.com>, "'Navid'" <silencer2020@yahoo.ca>, >xmlschema-dev@w3.org >Subject: RE: XML Schema: Alternating "unbounded" elements >Date: Fri, 18 Apr 2003 17:03:41 -0400 > >Anli Shundi suggests: > > >> something simpler like seems sufficient > > >> (f1*|f2*|f3*)* > >I think I'm correct in saying that the above accepts the same language as: > > (f1 | f2 | f3)* > >...as suggested in my mail of earlier today. > >Thanks. > >------------------------------------------------------------------ >Noah Mendelsohn Voice: 1-617-693-4036 >IBM Corporation Fax: 1-617-693-8676 >One Rogers Street >Cambridge, MA 02142 >------------------------------------------------------------------ > > > > > > > >Anli Shundi <ashundi@tibco.com> >Sent by: xmlschema-dev-request@w3.org >04/18/2003 01:58 PM > > > To: "'Navid'" <silencer2020@yahoo.ca>, Mohan Raj ><mohanrajd@hotmail.com>, >xmlschema-dev@w3.org > cc: (bcc: Noah Mendelsohn/Cambridge/IBM) > Subject: RE: XML Schema: Alternating "unbounded" elements > > > >something simpler like seems sufficient > >(f1*|f2*|f3*)* > ><schema > xmlns:tns="tns" > xmlns="http://www.w3.org/2001/XMLSchema" > targetNamespace="tns" > elementFormDefault="qualified" > > > <element name="record"> > <complexType> > <choice maxOccurs="unbounded"> > <element name="field1" type="tns:type" >maxOccurs="unbounded" >/> > <element name="field2" type="tns:type" >maxOccurs="unbounded" >/> > <element name="field3" type="tns:type" >maxOccurs="unbounded" >/> > </choice> > </complexType> > </element> > > <complexType name="type"> > <sequence> > <element name="value" type="string"/> > </sequence> > </complexType> ></schema> > > > > >Anli Shundi >TIBCO Software Inc. >www.tibco.com > > > -----Original Message----- > > From: Navid [mailto:silencer2020@yahoo.ca] > > Sent: Friday, April 18, 2003 1:16 PM > > To: Mohan Raj;
