      <Data property="MetaData/details">
        <String>This specification does not prescribe the use of :sp:element:`PropertyBreaks &lt;!Plant.Piping.PropertyBreak&gt;`
whenever piping properties change. For example, consider a :sp:element:`~Plant.Piping.PipeReducer`
where, by definition, the nominal diameter is changed. According to
the Proteus Specification, a new :sp:element:`~Plant.Piping.PipingNetworkSegment` must
begin immediately after the :sp:element:`~Plant.Piping.PipeReducer`. This 
:sp:element:`~Plant.Piping.PipingNetworkSegment` will have a different nominal diameter
than the one before. Thus, the property break information is available
without an explicit :sp:element:`!~Plant.Piping.PropertyBreak`. A :sp:element:`!~Plant.Piping.PropertyBreak` shall
be used to emphasize such a change. In a
:sp:element:`~Core.Diagram.Diagram`, a :sp:element:`!~Plant.Piping.PropertyBreak` is typically visualized by
a :sp:element:`~Core.Diagram.PropertyBreakShape`.

A single :sp:element:`!~Plant.Piping.PropertyBreak` can indicate the change of *several* properties
e.g., the nominal diameter *and* the piping class. It is recommended to
avoid such :sp:element:`PropertyBreaks &lt;!Plant.Piping.PropertyBreak&gt;` that concern several properties.
Instead, for each changed property a separate :sp:element:`!~Plant.Piping.PropertyBreak`
should be used. These :sp:element:`PropertyBreaks &lt;!Plant.Piping.PropertyBreak&gt;` should then be connected with
:sp:element:`DirectPipingConnections &lt;Plant.Piping.DirectPipingConnection&gt;`. In a
:sp:element:`~Core.Diagram.Diagram`, each :sp:element:`!~Plant.Piping.PropertyBreak` can then be visualized
by a separate :sp:element:`~Core.Diagram.PropertyBreakShape` symbol. In case a diagram contains
dedicated symbols for certain combinations of changed properties, it is still
admissible to use a single :sp:element:`!~Plant.Piping.PropertyBreak` for these combinations.</String>
