[OpenLayers-Dev] XMLHttpRequest.js license

based on my experience in other projects, it should be sufficient to include this in a comment at the top of XMLHttpRequest.js with a brief explanation of the issue and then we should be good to go.

For the record, I am wondering why it is a problem to include LGPL code in OpenLayers if it is used as a Library (unmodified)?  Roald's remark just seems to be that we *might* have a GPL infringement, that doesn't seem terribly convincing to me that there is a problem that we should be concerned about by including LGPL code.  Can anyone elaborate on whether this is actually a problem, what the problem is, or if there is not, in actual fact, a problem with including LGPL code.
