1. Description of <coverage> in <asset> says "Element has no attributes, but it can contain 0 or 1 <geographic_location> child elements. " Would be less convoluted as "...can optionally contain one <geographic_location child element."
2.Description of <unit> has an extraneous "name: meter" at the bottom.
3. List of values for up_axis includes X-UP; shd be X_UP (see bug 77 for same issue in 1.4.1 2nd ed. spec).
4. Default column for <unit> doesn't clearly/consistently format "name: meter".
