[osis-core] Canon regex

[Patrick Durusau]

Guys,

Suddenly occurred to me while working on Steve's regexes that canon is 
really just work at a different position. After all, if we are applying 
to to a variety of texts, the various parts of a canonical identifier 
may have letters/numbers as well and be separated by periods (full 
stops). The only real difference is that work comes before the ":" and 
canon comes after it.

In the osisID regex I will have to add the ":" in as required. But the 
canon regex should read as follows:

<xs:pattern value = "([\L\N\.]([\L\N\.]*)?)" />

By which I am trying to say, any letter or number combination, followed 
by a period is complusory, followed by any number of optional 
letter/number combinations that also end in a period (periods, hyphens, 
etc., being excluded from the canon name).

Onwards to grain and finally putting them all together. Yikes!

Patrick
