17.18.42 ST_HpsMeasure

This simple type specifies that its contents contain either:

• A positive whole number, whose contents consist of a measurement in half-points (equivalent to
• 1/144th of an inch), or
• A positive decimal number immediately followed by a unit identifier.

The contents of this measurement are interpreted based on the context of the parent XML element.

[Example: Consider an attribute value of 72 whose simple type is ST_HpsMeasure. This attribute value specifies a size of one-half of an inch or 36 points (72 halves of a point = 36 points = 0.5 inches). end example]

[Example: Consider an attribute value of 12.7mm whose type is ST_HpsMeasure. This attribute value specifies a size of 0.0127 meter or one-half of an inch or 36 points. end example]

This simple type is a union of the following types:

• The ST_PositiveUniversalMeasure simple type (22.9.2.12).
