''Important Note: there is no known use of this property or examples of it actually being used in a working way.''

[[XML/RelValue|RelValue]] is a type used for defining a single value relate to relating to size or position in the the UI coordinate system. See [[XML/RelDimension|RelDimension]] and [[XML/Dimension|Dimension]] for value pair use types. RelValue is used for properties such as [[XML_properties#FontHeight|FontHeight]] and [[XML_properties#TileSize|TileSize]].

== Summary ==

[[XML/RelValue|RelValue]] facilitates the 'Layout' mechanism in the WoW UI. See the [[XML/AbsDimension|AbsDimension]] and [[XML/Dimension|Dimension]] for numerical value pairs use types. RelValue is the 'scalar' property version in [[XML/Value|Value]], where <[[XML/AbsValue|AbsValue]]> is the 'unit based' value property version.

=== Example ===
''Note: this is an example for documentation completeness purposes. RelValue has no known working use at this time.''
 <Frame name="MyFrame">
   <Size x="200" y="200"/>
   <Layers>
     <Layer>
       <[[XML/FontString|FontString]] text="Bob" inherits="MyFont">
         <Size x="100" y="100"/>
         <[[XML/Value|FontHeight]]>
           <[[XML/RelValue|RelValue]] val="12.5"/>
         </FontHeight>
         <Anchors>
           <Anchor point="TOP"/>
         </Anchors>
       </FontString>
     </Layer>
   </Layers>
 </Frame>

This example demonstrates use of [[XML_properties#FontHeight|FontHeight]] using '''Rel''' values.
