-   For matching, the "Basic Filtering" matching scheme, defined in

-     A language range matches a
-     particular language tag if, in a case-insensitive comparison, it
-     exactly equals the tag, or if it exactly equals a prefix of the tag
-     such that the first character following the prefix is "-".

+   For matching, <xref target="RFC4647" x:sec="3" x:fmt="of"/> defines

-    <x:h>Note:</x:h> This use of a prefix matching rule does not imply that
-    language tags are assigned to languages in such a way that it is
-    always true that if a user understands a language with a certain
-    tag, then this user will also understand all languages with tags
-    for which this tag is a prefix. The prefix rule simply allows the
-    use of prefix tags if this is the case.

-   The language quality factor assigned to a language-tag by the
-   Accept-Language field is the quality value of the longest language-range
-   in the field that matches the language-tag. If no language-range
-   in the field matches the tag, the language quality factor
-   assigned is 0. If no Accept-Language header is present in the
-   request, the server
-   &SHOULD; assume that all languages are equally acceptable. If an
-   Accept-Language header is present, then all languages which are
-   assigned a quality factor greater than 0 are acceptable.
