I am trying to open the following xml file in Excel 2003 Pro SP2 without much
luck.
This file was originally a .gpx file extension and I changed the extension
to .xml.
From my understanding .gpx is supposed to be a standard xml file and if it
is I should be able to change the extension and open it in Excel. Please let
me know what is wrong with the file. I get the following error.

The following schema elements and structures cannot be mapped to a
worksheet. They will not be visible in the XML source task pane.
-any
-anyattribute
-substitution groups
-abstract elements
-recursive structures
-mixed content.
Do you want to continue adding this schema to your workbook?

I will post the text for the file separate
