The meaning of the "string" datatype?

["Costello, Roger L." <costello@mitre.org>]

Hi Folks,

Consider this XML Schema declaration:

   <element name="Author" type="string" />

I want to reconfirm my understanding of what the declaration means:

In an instance document:

    <Author>__________</Author>
                ^
                |
                |
The content of <Author> can be characters from any language - English, Chinese, Arabic, Italian, Greek, German, Spanish, Russian, etc - plus punctuation symbols plus math symbols. If I did my arithmetic correctly [1], the total number of different characters is: 1,112,000.

Furthermore, the length of the content of <Author> is unconstrained: it would be perfectly valid to place a billion characters between the start tag and end tag.

Do you agree?

/Roger

[1] The allowable characters for the string datatype is any character in these hex ranges:

Char    ::=    #x9 | #xA | #xD | [#x20-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF]
