xml schema problem

Hi

I am writing a schema for an XML document i would like the document to have a structure such as the the one below

------------------------------------------------------------

<?xml version="1.0"?>
<group xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation='lr2.xsd'>
<house ref="3" name="Waseem House">
<room ref="3443" type="Standard" beds="2">
<price day="2004-06-30">222.99</lrate_price>
<price day="2004-06-29">222.99</lrate_price>
</room>
</house>
</group>

-----------------------------------------------------------
This means the element price must have an attributre and an element value i cant get this to work in my schema, when i do this it says that the element price cant have a simple type "type" and a complex type attribute [i am using perl / xerces] my schema is below

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs='http://www.w3.org/2001/XMLSchema'>
<xs:element name="group">
<xs:complexType>
<xs:sequence>
<xs:element ref="house" minOccurs='1' maxOccurs='unbounded'/>
</xs:sequence>
</xs:complexType>
</xs:element>

<xs:element name="house">
<xs:complexType>
<xs:sequence>
<xs:element ref="room" minOccurs='1' maxOccurs='unbounded'/>
</xs:sequence>
<xs:attribute name="ref" type="xs:integer" use='required'/>
<xs:attribute name="name" type="xs:string" use='required'/>
</xs:complexType>
</xs:element>

<xs:element name="room">
<xs:complexType>
<xs:sequence>
<xs:element ref="price" type="lratetype" minOccurs='1' maxOccurs='unbounded'/>
</xs:sequence>
<xs:attribute name="ref" type="xs:integer" use='required'/>
<xs:attribute name="type" type="xs:string" use='required'/>
<xs:attribute name="beds" type="xs:integer" use='required'/>
</xs:complexType>
</xs:element>

<xs:element name="price" type="xs:decimal">
<xs:complexType>
<xs:attribute name="day" type="xs:date" use='required'/>
</xs:complexType>
</element>

</xs:schema>

----------------------------------------------------------

Im not sure what i am doing wrong as i need to make sure the text in the price element is of decimal , do i need to use the restriction syntax ?

I think maybe you need to looak at your xml file first.
It's not exactly well formed,
you should not put (xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation='lr2.xsd') into the root.
And (<price day="2004-06-30">222.99</lrate_price>) must be changed to
(<price day="2004-06-30">222.99</price>)
