I imported an Earth model into My Maps, then exported it to a KMZ. I unzipped the KMZ and ran the resulting doc.kml through a a validator (XmlValidator) against the XSD at http://schemas.opengis.net/kml/2.2.0/ogckml22.xsd.
The response?

Is this important? Will it bite me later? What, if anything, can or should be done?
I'm asking because I'm using the KML exported from Maps as a template for generating KML programmatically for use in Maps.
Strangely, the first instance of the markup <Style id="line-000000-1-normal"> is not on line 3319 but on 4022 being

More weirdness: I imported the kml into Fusion Charts and then exported it. The KML now has the style information before the placemarks, and validates perfectly.
Solution: Put the style information first.
