_type_conditions
Name:'_type_conditions'
Definition:
Codes defining conditions on the _type specification. 'su' permits a number string to contain an appended standard uncertainty number enclosed within parentheses. E.g. 4.37(5) 'esd' is a deprecated synonym for 'su', arising from the former use of the term 'estimated standard deviation' for 'standard uncertainty', and permitting a number string to contain an appended standard deviation within parentheses. E.g. 4.37(5) 'seq' permits data to be declared as a sequence of values separated by a comma <,> or a colon <:>. * The sequence v1,v2,v3,. signals that v1, v2, v3, etc. are alternative values. * The sequence v1:v2 signals that v1 and v2 are the boundary values of a continuous range of values satisfying the requirements of _enumeration for the defined item. Combinations of alternative and range sequences are permitted.
