+Output.SortAttr
+TYPE: bool
+VERSION: 3.1.2
+DEFAULT: false
+--DESCRIPTION--
+<p>
+  If true, HTML Purifier will sort attributes by name before writing them back
+  to the document, converting a tag like: <code>&lt;el b="" a="" c="" /&gt;</code>
+  to <code>&lt;el a="" b="" c="" /&gt;</code>. This is a workaround for
+  a bug in FCKeditor which causes it to swap attributes order, adding noise
+  to text diffs. If you're not seeing this bug, chances are, you don't need
+  this directive.
