| length is the number of units of length, where units of length varies
depending on the type that is being ???derived??? from.
The value of length ???must??? be a nonNegativeInteger.
Length is defined as:
- string length is measured in units of characters
- anyURI length is measured in units of characters
- hexBinary and base64Binary length is measured in octets (8bits) on
binary data
- list length is measured in number of list items
This is xml so length string applies to datatypes derrived from string.
Simon the spec says:
For string and datatypes ???derived??? from string, length will not always
coincide with "string length" as perceived by some users or with the number
of storage units in some digital representation. Therefore, care should be
taken when specifying a value for length and in attempting to infer storage
requirements from a given value for length.
Example:
<simpleType name='productCode'>
<restriction base='string'>
<length value='8' fixed='true'/>
</restriction>
</simpleType>
