I should possibly have said "your processing code _must_ pick" rather
than _will_ 

that is, there is nothing automatic or special about that
URL (I just found it with google) Essentially you need any identifying
string there for your processor to detect, but note that this is
processor specific behaviour, other MathML processors may either ignore
the definitionURL and treat the number in whatevr format they store real
numbers, or alternatively they may warn that they do not understand how
to process that definitionURL.
