I'm having difficulty writing my xml schema (.xsd) file. My xml file contains a recursive element para which in turn has mixed elements within.

The element para contains either text only or it contains 0 or more sub-elements para and/or it contains 0 or more element footnotes or/and it contains 0 or more elements emphasis.

Footnotes in turn may contain subelement para which in turn contains text and/or footnotes and/or emphasis, etc.

Here's my abcad.xsd file

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

	<xs:element name="content">
		<xs:complexType mixed="true">
			<xs:sequence>
				<xs:choice maxOccurs="unbounded">
					<xs:element name="para">
						<xs:complexType mixed="true">
							<xs:sequence minOccurs="0">
								<xs:element name="emphasis" type="xs:string" />
							</xs:sequence>
						</xs:complexType>
				
					<xs:element name="footnote" >
						<xs:complexType mixed="true">
							<xs:sequence minOccurs="0" maxOccurs="unbounded">
								<xs:element name="para" type="xs:string" />
							</xs:sequence>
						</xs:complexType>
					</xs:element>
					</xs:element>
				</xs:choice>
			</xs:sequence>
		</xs:complexType>
	</xs:element>

</xs:schema>

Here's my abcad.xml file

<?xml version="1.0" encoding="UTF-8"?>
<content xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="abcad.xsd">

Error: 16: cvc-complex-type.2.4.a: Invalid content was found starting with element 'footnote'. One of '{emphasis}' is expected.

Sorry. I shouldn't have been trying to make it recursive. I got it working.
