Description:

A complex number consists of a real and imaginary part. An element of type, complexNumber, will have two subelements:

realPart: The numeric value of the real part of the complex number.
imaginaryPart: The numeric value of the imaginary part of the complex number.

Proposed Usage:

This datatype was developed to support the Epicentre complex data type. Its intended usage is shown in the PEF complex element document. Usage as a useful datatype is shown in the following sample usage schema and sample XML.

Warning: The W3C Consortium is developing its own version of a complex number datatype which may vary slightly from this version.

XML Schema:

The schema and examples do not explicitly show the lines that set the namespaces.

All schema examples will use xsd: as the namespace for the schema tags and datatypes, and null for all the locally generated namespaces.

XML Examples will exclude namespace modifiers for clarity. Actual XML will probably need namespaces.

<xsd:complexType name="complexNumber">
  <xsd:sequence>
    <xsd:element name="realPart" type="xsd:double"/>
    <xsd:element name="imaginaryPart" type="xsd:double"/>
  </xsd:sequence>
</xsd:complexType>

Sample Usage Schema:

All elements are local. It is recommended that elementFormDefault be "qualified."

   <xsd:element name="rotationalComponent" type="complexNumber"/>

Sample XML:

   <rotationalComponent>
     <realPart>.80229</realPart>
     <imaginaryPart>.59693</imaginaryPart>
   </rotationalComponent>
