xs:documentation
<xs:documentation source = "anyURI
" xml:lang = "language
"> <!-- any well-formed XML markup --> </xs:documentation>
The xs:documentation
element appears exclusively inside xs:annotation
elements, where it
provides human-readable information about the schema or schema
element it's annotating. It has no effect on schema validation. It
can contain absolutely any XML markup: XHTML, DocBook, or just
plain text. The only restriction is that the contents must be
well-formed. Alternately, instead of or in addition to including
this information directly, the source
attribute can point to it using a
URI. The xml:lang
attribute can
indicate the language in which the description is written. You
could even include multiple xs:documentation
elements in different
languages.
