Strange, that's what I tried, it doesn't copy anything for me. What exactly is going to your clipboard, only the highlighted part, i.e.
<ID>
<loc>
<description>
Or something else as well? If it's just the above we could simply change the order of <loc> and <ID> and copy&paste should work.
And if someone finds out why I can't copy&paste from the map (works just fine from other windows) let me know.
