According to the spec
(http://www.w3.org/TR/2000/REC-DOM-Level-2-Style-20001113/css.html#CSS-CSSMediaRule)

- the insertRule(rule, index) method can raise the following exceptions:
HIERARCHY_REQUEST_ERR: Raised if the rule cannot be inserted at the specified
index, e.g., if an @import rule is inserted after a standard rule set or other
at-rule.
INDEX_SIZE_ERR: Raised if the specified index is not a valid insertion point.
NO_MODIFICATION_ALLOWED_ERR: Raised if this media rule is readonly.
SYNTAX_ERR: Raised if the specified rule has a syntax error and is unparsable.

- the deleteRule(index) method can raise the following exceptions:
INDEX_SIZE_ERR: Raised if the specified index does not correspond to a rule in
the media rule list.
NO_MODIFICATION_ALLOWED_ERR: Raised if this media rule is readonly.

We never raise exceptions for either method.
