Synopsis

<xs:minLength
           fixed          = xs:boolean : “false”
           id             = xs:ID

May be included in: xs:restriction (simple type), xs:restriction (simple content)

Description

xs:minLength is a facet that allows definition of the minimum length expressed in a unit that depends on the datatype. For most of the datatypes, the unit is the character as defined in the XML 1.0 Recommendation (i.e., Unicode characters defined by ISO/IEC 10646 that may be represented on more than 8 bits). The exceptions are the binary datatypes (xs:hexBinary and xs:base64Binary), for which lengths are expressed in number of bytes (8 bits) of binary data, and all the list datatypes, for which lengths are expressed in number of list items.

xs:minLength constrains the value space. In practice, this means that it is checked after whitespace replacement and collapsing, as defined by the xs:whiteSpace facet.

Restrictions

This is a logical length, which often has no direct relation on the size of storage needed for the value.

It is forbidden to define both xs:minLength and xs:length in the same restriction step. Although not ...
