XSD - trying to understand complextypes

XSD - trying to understand complextypes

(OP)
I have been given a set of XSD documents by a company in order to pass them data. They are a huge sprawling series of interconnecting types and it is taking hours to unravel it all.

I am fairly new to XML and completely new to XSD so I have been learning a lot, but I am stumped by one section of XML:

CODE --> XML

<xs:complexType name="btx" mixed="true">
		<xs:choice minOccurs="0" maxOccurs="unbounded">
			<xs:element ref="FT"/>
			<xs:element ref="P"/>
		</xs:choice>
	</xs:complexType>

	<xs:element name="P" type="btx"/>

	<xs:complexType name="ft" mixed="true">
		<xs:complexContent mixed="true">
			<xs:extension base="btx">
				<xs:attribute name="TYPE">
					<xs:simpleType>
						<xs:restriction base="xs:NMTOKEN">
							<xs:enumeration value="REFOJ"/>
							<xs:enumeration value="SUB"/>
							<xs:enumeration value="SUP"/>
						</xs:restriction>
					</xs:simpleType>
				</xs:attribute>
			</xs:extension>
		</xs:complexContent>
	</xs:complexType>

	<xs:element name="FT" type="ft"/> 

From what I can work out whenever an Element has a Type of "btx" it is supposed to contain text, a description or some information, but I can't work out where to put any text... All the other elements which contain text have a simpleType of xs:string. Can I assume that the "P" element can contain text?

If I can supply any extra code to make this more clear, please let me know.

Thanks very much.

RE: XSD - trying to understand complextypes

CODE --> XML

<xs:complexType name="btx" mixed="true"> 

When the mixed attribute is "true", character data is allowed to appear between the child elements of the complexType element being described.
