[ISO/IEC 29500-1 1st Edition]

characteristic (Single Characteristic)

This element specifies a single characteristic. The type of characteristic is defined by the name attribute.

[Example: A producer can inform the consumer that the computations used to calculate the stored numbers in the formulas belong to a value space expressed by ranges of the binary mantissa and exponent. A consumer can optionally check those characteristics to determine whether, for example, the values should be recalculated. The XML for this would be:

<additionalCharacteristics>
  <characteristic name='precisionMantissa' relation='gt' val='-9007199254740992'/>
  <characteristic name='precisionMantissa' relation='lt' val='9007199254740992'/>
  <characteristic name='precisionExponent' relation='ge' val='-1075'/>
  <characteristic name='precisionExponent' relation='le' val='970'/>
</additionalCharacteristics>

end example]

The possible values for this attribute are defined by the W3C XML Schema string datatype.

relation (Relationship of Value to Name)

Specifies how the contents of the value attribute should be interpreted in the context of this characteristic.

[Example: The following would specify that the application supports from 0 to 10,000 columns, and that column ranges should be interpreted accordingly:

<additionalCharacteristics>
  <characteristic name="numColumns" relation="le" val="10000"/>
  <characteristic name="numColumns" relation="ge" val="0"/>
</additionalCharacteristics>

end example]

The possible values for this attribute are defined by the ST_Relation simple type (§22.7.3.1).

val (Characteristic Value)

Specifies the value of the characteristic.

The possible values for this attribute are defined by the W3C XML Schema string datatype.

vocabulary (Characteristic Grammar)

Specifies a defining the characteristic grammar with which the name attribute value shall be interpreted.

If this attribute is omitted, then the default grammar (as defined above) shall be used.

The possible values for this attribute are defined by the W3C XML Schema anyURI datatype.
