Description:

The PEF angle element is a choice of a parsed angle (using the subelement, dms) or a quantity (using the subelement, quantity).

Proposed Usage:

This datatype was developed to support the Epicentre angle data types. It is intended as a direct mapping from Epicentre to an XML file.

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.

The defining file, either peftypes_u.xsd or peftypes_q.xsd, must be imported into the document building the application schema.

It is recommended that these elements and their subelements have a namespace qualifier. The recommended qualifier is 'pef'.

<xsd:element name="angle">
  <xsd:complexType>
    <xsd:choice>
      <xsd:element name="quantity" type="quantityType"/>
      <xsd:element name="dms" type="angleType"/>
    </xsd:choice>
  </xsd:complexType>
</xsd:element>

Sample Usage Schema:

The element is globally defined. It is recommended that elementFormDefault be "qualified."

  <element name="greenwich_longitude">
   <complexType>
    <sequence>
     <element ref="pef:angle"/>
    </sequence>
   </complexType>
  </element>

Sample XML:

The example will show namespace of 'pef'

  <greenwich_longitude>
   <pef:angle>
    <pef:dms>
     <pef:degree direction="E">12</pef:degree>
     <pef:minute>26</pef:minute>
     <pef:second>9.7882</pef:second>
    </pef:dms>
   </pef:angle>
  </greenwich_longitude>
