<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 will help with any performance concerns an application may have.

example: 
<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. ]
