/* MediaList is used to store 3 types of media related entities which mean the
 * same:
 *
 * Media Queries, Media Types and Media Descriptors.
 *
 * Media queries, as described in the Media Queries Level 3 specification, build
 * on the mechanism outlined in HTML4. The syntax of media queries fit into the
 * media type syntax reserved in HTML4. The media attribute of HTML4 also exists
 * in XHTML and generic XML. The same syntax can also be used inside the @media
 * and @import rules of CSS.
 *
 * However, the parsing rules for media queries are incompatible with those of
 * HTML4 and are consistent with those of media queries used in CSS.
 *
 * HTML5 (at the moment of writing still work in progress) references the Media
 * Queries specification directly and thus updates the rules for HTML.
 *
 * CSS 2.1 Spec (http://www.w3.org/TR/CSS21/media.html)
 * CSS 3 Media Queries Spec (http://www.w3.org/TR/css3-mediaqueries/)
