UomSymbol regex pattern rejects good values

[FuhuXia]

Here, the UomSymbol validation regex pattern [^: \n\r\t]+ in theory is supposed to reject all chars of colon, space, newline, carriage return, and tab. But we found out it actually rejects all n, r, t chars. Values such as decimalDegrees and feet will fail the validation.

If we rewrite the pattern to an equivalent [^:\s]+, then all looks ok.

@FuhuXia - Thanks for this fix! However, I don't understand why the exacty same file works fine in my validation scenario, but not in CKAN. Do you know what validation engine is in use?

@FuhuXia can you point me to an ISO doc where this is failing? thanks

Harvest errors for this doc:

Element '{http://www.isotc211.org/2005/gco}Measure', attribute 'uom': 'feet' is not a valid value of the union type '{http://www.opengis.net/gml/3.2}UomIdentifier'. (line 108)

feet and aaadecimalesrnbe fail because they contain n, r, t chars.
