datatypeLibraries :: DatatypeLibraries

List of all supported datatype libraries which can be used within the Relax NG validator modul.

datatypeEqual :: Uri -> DatatypeEqual

Tests whether a XML instance value matches a value-pattern.

The following tests are performed:

• 1. : does the uri exist in the list of supported datatype libraries
• 2. : does the library support the datatype
• 3. : does the XML instance value match the value-pattern

The hard work is done by the specialized DatatypeEqual function (see also: DatatypeCheck) of the datatype library.

datatypeAllows :: Uri -> DatatypeAllows

Tests whether a XML instance value matches a data-pattern.

The following tests are performed:

• 1. : does the uri exist in the list of supported datatype libraries
• 2. : does the library support the datatype
• 3. : does the XML instance value match the data-pattern
• 4. : does the XML instance value match all params

The hard work is done by the specialized DatatypeAllows function (see also: DatatypeCheck) of the datatype library.
