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.
n(optional)Provides a number-like designation that indicates an element’s position in a sequence
of similar elements. May not contain space characters.
Value conforms to data.WORD.
next(optional)Used to point to the next event(s) in a user-defined collection.

editing, or encoding. Its value must point to one or more identifiers declared in
the
document header.

attribute is the same as the language tag’s value.
