Hi +David Oesch
thanks for the feedback. I checked a KML file of the sample data straight from SpreadsheetMapper3 using the KML Validator, and I am seeing 2 errors. The first is a schema constraint violation due to the presence of the <atom:generator ...> tag, which is technically not a supported KML tag, even though it is part of the atom spec. I'll see about either getting this corrected in the validator, or removing it from SpreadsheetMapper. The second error is about the <atom:link ...> tag not containing the correct "ref" attribute. I believe this is an error in the validator, since the spec says that the "ref" attribute is not required, and the KML file does not contain one. I'll check with the experts on this one and get back to you. Are you seeing other errors in addition to the ones above? Thanks!
