How represent 24-bit data types in XML Schema? Limits?

[Ed Sutton]

I have data from an embedded device that I want to represent as an XML
schema. Each data sample in the device's data log consists of a 24-bit
pressure value plus a 1 byte temperature value. I am an XML schema newbie.

A 24-bit unsigned integer value has a range of 0 to 8388607. Is there some
way I can represent this in an XML schema?

Here is what the data looks like:

<DataLog>
<Sample>
<Pressure>12245 6></Pressure>
<Temperature>23 </Temperature>
</Sample>
<Sample>
<Pressure>13224 5></Pressure>
<Temperature>27 </Temperature>
</Sample>
<Sample>
<Pressure>17224 5></Pressure>
<Temperature>32 </Temperature>
</Sample>
</DataLog>

What would a logical XML schema look like?

<xs:complexTy pe name="LogData" >
<xs:complexTy pe name="Sample" >
<xs:element name="Pressure" type="xs:???">
<xs:element name="Temperatu re" type="xs:unsign edByte">
</xs:complexType>
</xs:complexType>

Thanks in advance for any tips or suggestions,

-Ed

<xs:element name="Pressure" >
<xs:simpleTyp e>
<xs:restricti on base="xs:int">
<xs:minInclusiv e value="0"/>
<xs:maxInclusiv e value="8388607"/>
</xs:restriction>
</xs:simpleType>
</xs:element>
