21.4.2.17 layoutDefHdr (Layout Definition Header)
This element is the header information representing the minimum knowledge needed by an application to preload information about a layout definition. This preloading allows for the actual load of the layout definition to occur at a later time which helps with any performance concerns an application might have.
[Example: Consider the following example of a layoutDefHdr within a DrawingML diagram:
<layoutDefHdr uniqueId="urn:layout/default">
<title val="Basic Block List" />
<desc val="" />
<catLst>
<cat type="list" pri="1000" />
</catLst>
</layoutDefHdr>
In this example we define a title along with a category and prioritization for the diagram referenced by the uniqueId of urn:layout:default. end example]
