`<cxn>` (Connection)

This element defines a connection between two points. A connection defines a relationship between two points in a diagram.

example:

<cxnLst>
	<cxn modelId="7" srcId="0" destId="1" srcOrd="0" destOrd="0"/>
	<cxn modelId="8" srcId="0" destId="2" srcOrd="1" destOrd="0"/>
	<cxn modelId="9" srcId="0" destId="3" srcOrd="2" destOrd="0"/>
	<cxn modelId="10" srcId="0" destId="4" srcOrd="3" destOrd="0"/>
	<cxn modelId="11" srcId="0" destId="5" srcOrd="4" destOrd="0"/>
	<cxn modelId="12" srcId="0" destId="6" srcOrd="5" destOrd="0"/>
</cxnLst>

In this example we see 6 <cxn> elements defined within a <cxnLst> element (§5.9.3.3). In this example, a relationship is being defined between point 0 and every other point in the diagram. ]

Attributes	Description
`<destId>` (Destination Identifier)	The model identifier of the destination point for a connection. <cxn modelId="10" srcId="0" destId="4" srcOrd="3" destOrd="0"/> In this example we see the destination identifier referencing a point who's model identifier is `4`. ] The possible values for this attribute are defined by the ST_ModelId simple type (§5.9.7.42).
`<destOrd>` (Destination Position)	The relative position of the destination point among it's siblings. <cxn modelId="10" srcId="0" destId="4" srcOrd="3" destOrd="0"/> In this example we see the destination position is `0`. This means that it is ranked first among its siblings if there are sibling points present. ] The possible values for this attribute are defined by the XML Schema unsignedInt datatype.
`<modelId>` (Model Identifier)	The unique identifier associated with this `<cxn>`. <cxn modelId="10" srcId="0" destId="4" srcOrd="3" destOrd="0"/> In this example we see the model identifier is `10`. ] The possible values for this attribute are defined by the ST_ModelId simple type (§5.9.7.42).
`<parTransId>` (Parent Transition Identifier)	The model identifier of the point representing the parent transition. An example of a parent transition can be thought of as the shape connecting two points, such as an arrow in the diagram. The unique identifier associated with this `<cxn>`. <cxn modelId="10" srcId="0" destId="4" srcOrd="3" destOrd="0" parTransId="9" sibTransId="5"/> In this example we see the parent transition identifier is referencing a point who's model identifier is `9`. ] The possible values for this attribute are defined by the ST_ModelId simple type (§5.9.7.42).
`<presId>` (Presentation Identifier)	The unique identifier of the layout associated to the `<cxn>` (only the active presentation (layout) is saved so all the presId's in the file should be the same). <cxn modelId="10" type="presParOf" srcId="0" destId="4" srcOrd="3" destOrd="0" presId="urn:sampleLayouts/layout1"/> In this example we see the presentation identifier is `urn:sampleLayouts/layout1`. ] The possible values for this attribute are defined by the XML Schema string datatype.
`<sibTransId>` (Sibling Transition Identifier)	The model identifier of the point representing the sibling transition. An example of a sibling transition can be thought of as the shape connecting two points, such as an arrow in the diagram. <cxn modelId="10" srcId="0" destId="4" srcOrd="3" destOrd="0" parTransId="9" sibTransId="5"/> In this example we see the sibling transition identifier is referencing a point who's model identifier is `5`. ] The possible values for this attribute are defined by the ST_ModelId simple type (§5.9.7.42).
`<srcId>` (Source Identifier)	The model identifier of the source point for a connection. <cxn modelId="10" srcId="0" destId="4" srcOrd="3" destOrd="0"/> In this example we see the souce identifier referencing a point who's model identifier is `0`. ] The possible values for this attribute are defined by the ST_ModelId simple type (§5.9.7.42).
`<srcOrd>` (Source Position)	The relative position of the source point among it's siblings. <cxn modelId="10" srcId="0" destId="4" srcOrd="3" destOrd="0"/> In this example we see the source position is `3`. This means that it is ranked third among its siblings. ] The possible values for this attribute are defined by the XML Schema unsignedInt datatype.
`<type>` (Point Type)	The type of point, which will correspond to a connection in this case. <cxn modelId="10" type="presParOf" srcId="0" destId="4" srcOrd="3" destOrd="0" presId="urn:sampleLayouts/layout1"/> In this example we see the point type is defined as `presParOf`. ] The possible values for this attribute are defined by the ST_CxnType simple type (§5.9.7.23).
