/**
* Returns an HTML element in a string. The major advantage here over
* manually typing out the HTML is that it will escape all attribute
* values. If you're hardcoding all the attributes, or there are none, you
- * should probably type out the string yourself.
+ * should probably just type out the html element yourself.
*
* This is quite similar to Xml::tags(), but it implements some useful
* HTML-specific logic. For instance, there is no $allowShortTag
* parameter: the closing tag is magically omitted if $element has an empty
* content model. If $wgWellFormedXml is false, then a few bytes will be
- * shaved off the HTML output as well. In the future, other HTML-specific
- * features might be added, like allowing arrays for the values of
- * attributes like class= and media=.
+ * shaved off the HTML output as well.
*
* @param $element string The element's name, e.g., 'a'
* @param $attribs array Associative array of attributes, e.g., array(
- * 'href' => 'http://www.mediawiki.org/' ). See expandAttributes() for
+ * 'href' => 'http://www.mediawiki.org/' ). See expandAttributes() for
* further documentation.
* @param $contents string The raw HTML contents of the element: *not*
* escaped!
* For instance, it will omit quotation marks if $wgWellFormedXml is false,
* and will treat boolean attributes specially.
*
+ * Attributes that should contain space-separated lists (such as 'class') array
+ * values are allowed as well, which will automagically be normalized
+ * and converted to a space-separated string. In addition to a numerical
+ * array, the attribute value may also be an associative array. See the
+ * example below for how that works.
+ * @example Numerical array
+ * <code>
+ * Html::element( 'em', array(
+ * 'class' => array( 'foo', 'bar' )
+ * ) );
+ * // gives '<em class="foo bar"></em>'
+ * </code>
+ * @example Associative array
+ * <code>
+ * Html::element( 'em', array(
+ * 'class' => array( 'foo', 'bar', 'foo' => false, 'quux' => true )
+ * ) );
+ * // gives '<em class="bar quux"></em>'
+ * </code>
+ *
* @param $attribs array Associative array of attributes, e.g., array(
* 'href' => 'http://www.mediawiki.org/' ). Values will be HTML-escaped.
* A value of false means to omit the attribute. For boolean attributes,
# and we'd like consistency and better compression anyway.
