 When working with HTML attributes in various functions we use something
 like `[\'"](.+?)[\'"]` to match the attribute value. Although not used
 much in attribute values, such an approach breaks when a single or double
 quote is intentionally part of the value:

 * `attr="val'ue"`
 * `attr='val"ue'`

 Some of these are new 3.6 functions, mostly around media.
