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]

Attributes |
Description | ||||||||||||||||||||||||||||||||||||||||||||||||
name (Name of Characteristic) |
Specifies the name of the characteristic. There are no constraints on the value of the name attribute, but each name shall be associated with a specific vocabulary via the vocabulary attribute.
The values defined by this Standard shall be associated with a null vocabulary value, and are as follows:
The possible values for this attribute are defined by the 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>
The possible values for this attribute are defined by the ST_Relation simple type (§7.7.3.1). | ||||||||||||||||||||||||||||||||||||||||||||||||
val (Characteristic Value) |
Specifies the value of the characteristic.
The possible values for this attribute are defined by the XML Schema string datatype. | ||||||||||||||||||||||||||||||||||||||||||||||||
vocabulary (Characteristic Grammar) |
Specifies a URI 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 XML Schema anyURI datatype. |
