Mucho Gracias Ken!  I will note this in my notebook of "references that 
may come in handy again some day" section :)

Yeah, the "2004-11-15" not being considered a number I knew, but without 
referencing the spec I was unsure of the exact nature of the number 
function and what the intended primary purpose was.

Wait, are you refering to attember a cast to a number and then 
comparing?  Obviously if compared to another string of equal value it 
would evaluate to true... or am I missing something that is important to 
understand in the comparison of this particular string?

It does, as always!  Thanks Ken!
