Better to teach catalogers to adhere to the standard, which rightfully 
recognizes that cm is an internationally agreed upon metric symbol which 
does not include a period.  The standard spells out the content of the 
data to be included.  To record the value cm with a period is wrong.  RDA 
does not require ISBD punctuation, which is really the issue here.  In my 
mind it is better to forget to input a period after cm when there is a 490 
present than to always input an incorrect period after the metric symbol.
