atleast, atmost, confidence, extent, max, min, unit

atleast(optional)Gives a minimum estimated value for an approximate measurement. Value is a decimal number.

atmost(optional)Gives a maximum estimated value for an approximate measurement. Value is a decimal number.

confidence(optional)Specifies the degree of statistical confidence (between zero and one) that a value falls within the range specified by min and max, or the proportion of observed values that fall within that range. Value conforms to data.CONFIDENCE.

extent(optional)Captures a measurement, count, or description. When extent contains a numeric value, use the unit attribute to indicate the measurement unit. Value is plain text.

max(optional)Where the measurement summarizes more than one observation or a range of values, supplies the maximum value observed. Value is a decimal number.

min(optional)Where the measurement summarizes more than one observation or a range of values, supplies the minimum value observed. Value is a decimal number.

unit(optional)Indicates the unit of measurement. Suggested values are: "byte" (Byte.), "char" (Character.), "cm" (Centimeter.), "deg" (Degree.), "in" (Inch.), "issue" (Serial issue.), "ft" (Foot.), "m" (Meter.), "mm" (Millimeter.), "page" (Page.), "pc" (Pica.), "pt" (Point.), "px" (Pixel.), "rad" (Radian.), "record" (Record.), "vol" (Serial volume.), "vu" (MEI virtual unit.)
