-<p>The Symbian platform uses the principle of format layering
-in which new formatting is added as a layer onto the previous layer of formatting.
-The following diagram shows a less efficient technique for applying format
-layering to text. The inefficiency arises because each format layer stores
-not only the new attribute which it introduces, but also every attribute which
-it inherits from the preceding format layer. </p>

-<p>The Symbian platform avoids this inefficiency by using the system of <keyword>based-on
-links</keyword>. Here, each new layer adds attributes in a natural way without
-restating all attributes previously set. A based-on link is a pointer to the
-format layer whose attributes are inherited by another layer. For example,
-when the italic attribute is applied to a region of bold text, the new layer
-stores only the italic attribute and a pointer to the previous attribute layer.
-Chains of format layers can thus be formed, with each layer based on the previous
-one. In order to determine a character or paragraph’s <keyword>effective format</keyword>,
-a chain of format layers must typically be examined. The final layer in the
-chain of based on links is the one whose based on link is NULL and is not
-therefore based upon any other layer.</p>
-<p>This method is demonstrated in the following two diagrams, in which each
-arrow represents a based-on link.</p>
