XML facet constraint attributes

The following attributes are facet constraints depending on the XSD data type used on a simple BDL variable to restrict the allowed value-space.

(Notice that some attributes are allowed only on some XSD data types).

Several facet constraints can be set on the same data type, and a mandatory values is expected ( for example, XSDMinLength="8".)

Table 1. Facet constraints between simple BDL and XML data types
Attribute	Definition
XSDLength	Define the exact number of XML character or bytes.
XSDMinLength	Define the minimum number of XML character or bytes.
XSDMaxLength	Define the maximum number of XML character or bytes.
XSDEnumeration	Define a list of allowed values separated by the character \|.
XSDWhiteSpace	Perform a XML string manipulation before serialization or deserialization.
XSDPattern	Define the regular expression the value has to match.
XSDMinInclusive	Define the inclusive minimum value based on the data type where it is set.
XSDMaxInclusive	Define the inclusive maximum value based on the data type where it is set.
XSDMinExclusive	Define the exclusive minimum value based on the data type where it is set.
XSDMaxExclusive	Define the exclusive maximum value based on the data type where it is set.
XSDTotalDigits	Define the total number of digits.
XSDFractionDigits	Define the number of digits of the fraction part.
