On the sample dirty.xml that is 13 findings, 9 errors and 4 warnings, across all 4 party address blocks; on clean.xml it is 0. The 6 errors: (1) unstructured_only, address held only in AdrLine with no TwnNm and no Ctry; (2) no_country, structured block with no Ctry; (3) no_town, hybrid block with no TwnNm; (4) dup_in_adrline, a value in both a dedicated element and an AdrLine; (5) adrline_max2, more than 2 AdrLine occurrences; (6) ctry_code, a Ctry that is not 2 upper-case letters. The 3 warnings: adrline_70, charset, bldgnb_in_strtnm.
