// country lables make 95% of the size of the file !!! therefore this attempts to reduce this a bit
//
// EM2 STRUCTURE: each variable has n structures of the form below for n countries that describe the variable:
// <CountryLabel> <ID>...</ID><VariableID>...</VariableID><Country>..</Country><Label>...</Label></CountryLabel>
//
// EM3 STRUCTURE (per variable): <Labels><![CDATA[c1°c1-lable|c2°c2-label|...]]></Labels> (note: CDATA only once required)
// e.g. <Labels><![CDATA[bg°Unemployment benefit (обезщетениe за безработица)|cy°Unemployment benefits from Social Insurance Fund|dk°Unemployment benefits and similar benefits (Arbejdsløshedsdagpenge og andre A- kasseydelser)|ee°unemployment insurance benefit (töötukindlustushüvitis)|el°unemployment insurance benefit (επίδομα ανεργίας)|es°Unemployment insurance (Prestación por desempleo)|fi°Earnings-related unemployment allowance|fr°Contributory unemployment benefit (ARE)|ie°jobseekers benefit (mainly)|lt°unemployment insurance benefit (nedarbo draudimo išmoka)|pt°benefit : unemployment : contributory|si°unemployment wage compensation (denarno nadomestilo za primer brezposelnosti)|sk°Contributory unemployment benefit|uk°JSA contributory|HR°unemployment benefit]]></Labels>
