This element specifies a rule entry in a rules element rule set that describes how a certain shape or set of shapes behaves during editing.

[Example: The following rule defines a connection between two shapes. The shape with id _s1036 connects shape _s1033 to _s1032:

<o:shapelayout v:ext="edit">

<o:rules v:ext="edit">

<o:r id="V:Rule1" type="connector" idref="#_s1036">

<o:proxy start="" idref="#_s1033" connectloc="0"/>

<o:proxy end="" idref="#_s1032" connectloc="2"/>

</o:r>

</o:rules>

</o:shapelayout>

end example]
