I'm not surprised that our American friends have weighed in with their own version of The Queen's English. It is, of course, a reflection that some parts of the American version of English are actually more linguistically pure [i.e. dating back to the 17th Century] than that which has subsequently evolved on this sceptre'd isle [please note the possessive there

].*
I have always worked in accordance with the principles of
JSP 101 which could be summarised as 'keep it simple'. Extraneous or optional apostrophes do not conform with that tenet.
