+Font size has slightly different priorities - the size provided by the platform is a logical
+size, and can be mapped to physical point sizes using style sheets. There is a default set of
+sizes defined for DALi, and these can be overridden by application specific stylesheets. Thus
+the priorities are:
+
+|  |  |  |
+|--|--|--|
+| Priority 1 | Size set by markup string. | Will override the style set through the stylesheets. |
+| Priority 2 | Physical Size set by application style sheet | |
+| Priority 2 | Logical Size set by application style sheet | Mapping from platform logical to physical |
+| Priority 3 | Logical Size set by DALi style sheet | Mapping from platform logical to physical |
