[Xml-compile] XML::Compile v0.91

[Drew Taylor]

I think I've come across a bug in 0.91 regarding minOccurs. I've tried  
to simplify down things as much as possible w/o removing the possible  
sources of trouble.

The new error message I got is: "error: no match for required block  
`DestinationSubPref' at {http://www.opentravel.org/OTA/ 
2003/05}TTI_ProductSearchRQ/SearchCriteria/DestinationPref". In a  
nutshell, it seems to be getting confused about the "minOccurs"  
attributes. Both the DestinationPref and DestinationSubPref have  
minOccurs=0, so I can't imagine why the SubPref would be required.

My SOAP client looks like:

my $client = XML::Compile::WSDL11->new($xml_file);
# import the various schema files
$client->compileClient(%params);
my ($answer, $trace) = $client->( { body => $params } );

And $params is:
# $VAR1 = {
#   'Version' => 1,
#   'CurrencyCode' => 'EUR',
#   'SearchCriteria' => {
#     'SearchDateRange' => {
#       'Start' => '2009-02-21',
#       'Duration' => 'P7N'
#     },
#     'DestinationPref' => [
#       {
#         'Code' => 'BBVT'
#       }
#     ],
#     'CustomerCounts' => {
#       'CustomerCount' => [
#         {
#           'Code' => 10,
#           'Quantity' => 3
#         }
#       ]
#     }
#   },
#   'POS' => { ... },
# };

A much simplified fragment of the schema is:
	<xs:element name="TTI_ProductSearchRQ">
		<xs:complexType>
			<xs:sequence>
				<xs:element name="POS" type="POS_Type" minOccurs="0"/>
				<xs:element name="SearchCriteria">
					<xs:complexType>
						<xs:sequence>

						</xs:sequence>
					</xs:complexType>
				</xs:element>
			</xs:sequence>
			<xs:attributeGroup ref="OTA_PayloadStdAttributes"/>
			<xs:attributeGroup ref="MaxResponsesGroup"/>
			<xs:attributeGroup ref="CurrencyCodeGroup"/>
		</xs:complexType>
	</xs:element>
	<xs:complexType name="DestinationPrefType">

		<xs:attribute name="Name" type="StringLength1to32" use="optional"/>
