+  <p>In some other writing systems,
+    <a>soft wrap opportunities</a> are based on orthographic syllable boundaries,
+    not word boundaries.
+    Some of these systems, such as Javanese and Balinese,
+    are similar to Thai and Lao in that they
+    require analysis of the text to find breaking opportunities.
+    In others such as Chinese (as well as Japanese, Yi, and sometimes also Korean),
+    each syllable tends to correspond to a single <a>typographic letter unit</a>,
+    and thus line breaking conventions allow the line to break
+    anywhere <em>except</em> between certain character combinations.
+    Additionally the level of strictness in these restrictions
+    varies with the typesetting style.
 
   <p>CSS does not fully define where <a>soft wrap opportunities</a> occur;
     however some controls are provided to distinguish common variations.
