/** |

|
|
|
* The type xsd:language represents a natural language identifier, generally used to indicate the language of a |
|
6
|
|
|
* document or a part of a document. Before creating a new attribute of type xsd:language, consider using the xml:lang |
|
7
|
|
|
* attribute that is intended to indicate the natural language of the element and its content. |
|
8
|
|
|
* |
|
9
|
|
|
* Values of the xsd:language type conform to RFC 3066, Tags for the Identification of Languages. |
|
10
|
|
|
* The three most common formats are: |
|
11
|
|
|
* |
|
12
|
|
|
* For ISO-recognized languages, the format is a two- or three-letter, (usually lowercase) language code that |
|
13
|
|
|
* conforms to ISO 639, optionally followed by a hyphen and a two-letter, (usually uppercase) country code that |
|
14
|
|
|
* conforms to ISO 3166. For example, en or en-US. |
|
15
|
|
|
* |
|
16
|
|
|
* For languages registered by the Internet Assigned Numbers Authority (IANA), the format is i-langname, where |
|
17
|
|
|
* langname is the registered name. For example, i-navajo. |
|
18
|
|
|
* |
|
19
|
|
|
* For unofficial languages, the format is x-langname, where langname is a name of up to eight characters |
|
20
|
|
|
* agreed upon by the two parties sharing the document. For example, x-Newspeak. |
|
21
|
|
|
* |
|
22
|
|
|
* Any of these three formats may have additional parts, each preceded by a hyphen, which identify additional |
|
23
|
|
|
* countries or dialects. Schema processors will not verify that values of the xsd:language type conform to the above |
|
24
|
|
|
* rules. They will simply validate based on the pattern specified for this type. |
