Why are all my schema links broken?

D._Pendleton

When I open an exported .GPX from Basecamp, my editor flags nearly all schema links as broken. Does anyone know why?

The XML is as follows:

<?xml version="1.0" encoding="utf-8"?>
<gpx creator="Garmin Desktop App"
     version="1.1"
     xsi:schemaLocation="http://www.topografix.com/GPX/1/1 http://www.topografix.com/GPX/1/1/gpx.xsd http://www.garmin.com/xmlschemas/WaypointExtension/v1 http://www8.garmin.com/xmlschemas/WaypointExtensionv1.xsd http://www.garmin.com/xmlschemas/TrackPointExtension/v1 http://www.garmin.com/xmlschemas/TrackPointExtensionv1.xsd http://www.garmin.com/xmlschemas/GpxExtensions/v3 http://www8.garmin.com/xmlschemas/GpxExtensionsv3.xsd http://www.garmin.com/xmlschemas/ActivityExtension/v1 http://www8.garmin.com/xmlschemas/ActivityExtensionv1.xsd http://www.garmin.com/xmlschemas/AdventuresExtensions/v1 http://www8.garmin.com/xmlschemas/AdventuresExtensionv1.xsd http://www.garmin.com/xmlschemas/PressureExtension/v1 http://www.garmin.com/xmlschemas/PressureExtensionv1.xsd http://www.garmin.com/xmlschemas/TripExtensions/v1 http://www.garmin.com/xmlschemas/TripExtensionsv1.xsd http://www.garmin.com/xmlschemas/TripMetaDataExtensions/v1 http://www.garmin.com/xmlschemas/TripMetaDataExtensionsv1.xsd http://www.garmin.com/xmlschemas/ViaPointTransportationModeExtensions/v1 http://www.garmin.com/xmlschemas/ViaPointTransportationModeExtensionsv1.xsd http://www.garmin.com/xmlschemas/CreationTimeExtension/v1 http://www.garmin.com/xmlschemas/CreationTimeExtensionsv1.xsd http://www.garmin.com/xmlschemas/AccelerationExtension/v1 http://www.garmin.com/xmlschemas/AccelerationExtensionv1.xsd http://www.garmin.com/xmlschemas/PowerExtension/v1 http://www.garmin.com/xmlschemas/PowerExtensionv1.xsd http://www.garmin.com/xmlschemas/VideoExtension/v1 http://www.garmin.com/xmlschemas/VideoExtensionv1.xsd"
