Requirements Class
http:www.opengis.netspecarml2.0reqmodel
Target Type Encoding
Requirement
http:www.opengis.netspecarml2.0reqmodelgeneralxsd_verification Any ARML 2.0 XML encoding shall validate correctly against the XSD defined in section 7.
This chapter defines an XML serialization of the ARML 2.0 object model. The XML serialization is defined in XSD. The following XSD header, namespaces and imports are used:
xsd:schema xmlns:xsd=http:www.w3.org2001XMLSchema targetNamespace=
http:www.opengis.netarml2.0 xmlns=
http:www.opengis.netarml2.0 xmlns:xlink=http:www.w3.org1999xlink
xmlns:gml= http:www.opengis.netgml3.2
elementFormDefault=qualified version=2.0

7.1 Document Structure
The root element of the document is arml, which contains the following elements:
The ARElements element, containing a list of ARElement objects.
Multiple optional style elements, including and optional type‐attribute that allows the specification of the style‐mime type typically textcss.
Multiple optional script elements, including and optional type‐attribute that allows the specification of the script‐mime type typically textjavascript.
Requirement
http:www.opengis.netspecarml2.0reqmodelgeneralroot_element arml is the root element of the encoding and shall be present.
Requirement
http:www.opengis.netspecarml2.0reqmodelARElementcontainer Only objects derived from ARElement are allowed as immediate child elements in the ARElements
tag.
