Error

Can anyone help me solve the following error:

“The 'http://www.papdis.org/schema/PAPDISDocument/v1:Country' element is invalid - The value 'United Kingdom of Great Britain and Northern Ireland' is invalid according to its datatype 'http://www.papdis.org/schema/PAPDISDocument/v1:AlphaNumericSymbolsString35Type' - The actual length is greater than the MaxLength value.”

It's bewildering because the error is new, but I haven't changed any settings.
Based on the code error, it looks like the 52 characters for “united kingdom etc blah blah” is too long.
