att.extent

Provides attributes for describing the size of an entity.
Module
Attributes
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. Allowed 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.)
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.
(MEI.shared) Attributes that record the unit of measurement in which a value is expressed.
unit(optional)Indicates the unit of measurement. Allowed 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.)
(MEI.shared) Groups attributes that describe a numerical range.
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.
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.
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.
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.
Component declarations that are shared between two or more modules.
