Changed typeCode to classCode and added a non-breaking space to codeSystemName
<observation typeCode='OBS' ...
<observation classCode='OBS' ...
(typeCode isn't a valid attribute. classCode is required.)
Also, there are no quotation marks on methodCode/@codeSystemName (although this is minor since the element is struck out anyway).
