Basic syntax:

<property_list>
          <property pid="p1">
               <attref name="aname_1_1"/>
               ...

          </property>
		...
		<property pid="pn">

          </property>
</property_list>

• Properties are defined in <property_list>…</property_list> section. This section must contain all properties which are used in ARD diagram.
• Single property is defined by <property> tag, with following parameters:

• Single property contains any number of attributes. List of attributes we can define by <attref> tag with following parameters:

Basic syntax:

     <tph>
          <trans src="p1" dst="p2"/>
          <trans src="p2" dst="p3"/>
          <trans src="p2" dst="p4"/>
		...
          <trans src="pn" dst="pm"/>
     </tph>

• TPH diagram is definied in <tph>…</tph> section. TPH diagram contains relations called branches.

• Branch defining begins the <trans> tag, which has following parameters:

Basic syntax:

<ard>
     <dependency independent="p1" dependent="p2"/>
     <dependency independent="p2" dependent="p3"/>
     ...
     <dependency independent="px" dependent="py"/>
     ...
     <dependency independent="px" dependent="pz"/>
</ard>

• Dependencies definig begins <ard> tag. This tag hasn't parameters. Each dependence is defined as pair of properties, where the first independent is the property tag name independed from the second property dependent.
