GT1_11_GuarantorRelationShip - The node cannot repeat but repetition delimiter was found

Hi,

 This is how the <xs:element minOccurs="0" maxOccurs="unbounded" name="GT1_GuarantorSegment" type="ns0:GT1" /> is defined in the DFT_P03_231_DEF.xsd schema.

I am trying to get the Gaurantor relationship to the patient from the GT1_11_GuarantorRelationShip root node by mapping our own proprietary schema. I am getting the below error in the Admin console when I deployed the solution

Error # 1
Segment Id: GT1_GuarantorSegment
Sequence Number: 1
Field Number: 11
Error Number: 207
Error Description: Application internal error
Encoding System: HL7nnnn
Alternate Error Number: Z100
Alternate Error Description: The node cannot repeat but repetition delimiter was found
Alternate Encoding System: HL7-BTA

I tried changing the maxOccurs to "1" but no luck.

Can some one help me how do I changed or modfiy the GT1_GuarantorSegment element in the schema?

Thanks in advance,

L
