By default, all output of format **text/html** (the default format) will be passed through it. It is controlled using the __clean__ parameter of the <out> tag. The features to be used should be listed in this parameter's value, separated by whitespace. Here are the features available: * __pack__ - Compress the HTML, removing all white space that is not part of an attribute's value, or inside <xmp> or <pre> tags. * __indent__ - ''Pretty-print'' the HTML, indenting tags appropriately, except for text and markup inside <xmp> or <pre> tags. * __nocomments__ - Trim all comments. * __addimgsizes__ - Add image sizes to <img> tags if they do not already specify them. * __cleanattrs__ - Quote all attributes in opening tags, and lowercase all tag names. * __addxmlslashes__ - Add XML-style slashes to the end of empty-element tags, such as <hr>, <img> etc. * __fixcolors__ - Fix colors that do not start with a # character, so that they do. The feature string __all__ can be used to include all cleaning modes. The default mode is ##pack addimgsizes cleanattrs addxmlslashes fixcolors indent##.
