XML Spy had no trouble with you example.  Here is the schema it generated using one set of options -

<?xml version="1.0" encoding="UTF-8"?>
<!--W3C Schema generated by XMLSPY v2004 rel. 3 U (http://www.xmlspy.com)-->
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"; elementFormDefault="qualified">
	<xs:element name="a">
		<xs:complexType>
			<xs:sequence>
				<xs:element name="a1">
					<xs:complexType>
						<xs:sequence>
							<xs:element name="b" type="bType"/>
						</xs:sequence>
					</xs:complexType>
				</xs:element>
				<xs:element name="a2">
					<xs:complexType>
						<xs:sequence>
							<xs:element name="b" type="bType"/>
						</xs:sequence>
					</xs:complexType>
				</xs:element>
			</xs:sequence>
		</xs:complexType>
	</xs:element>
	<xs:complexType name="bType">
		<xs:sequence>
			<xs:element name="c" type="xs:string"/>
		</xs:sequence>
	</xs:complexType>
</xs:schema>
