+<P>Matching takes place on attribute values in the document tree. For
+document languages other than HTML, default attribute values may be
+defined in a <span class="index-inst" title="DTD">DTD</span>. Style
+sheets should be designed so that they work even if a DTD does not
+accompany a document.
+
+<!-- Fix this example from Martin
+<P>For an element EXAMPLE with a DTD fragment of
+
+<!ATTLIST ex_attribute ... default-value [Bert, please complete here]
+
+if the style sheet contains a rule
+
+EXAMPLE[ex_attribute=default-value] { ... property settings ... }
+EXAMPLE[ex_attribute=other-value] { .......}
+
+then to catch the cases where this attribute is set by default,
+and not explicitly, the following rule might be added:
+
+EXAMPLE { ... the same property settings ... }
+
+Because this selector is less specific that a selector with
+another specific attribute value, it will only be used for
+the default case. Care has to be taken that all other attribute
+values that don't get the same style as the default value are
+explicitly covered.
