</span>I'm not sure that those restrictions on modifications are incompatible<br>
with Open Source Definition. Apache 2 is an Open Source license, despite<br>
that it has a yet stronger restriction on modification:<br>

In short: if you modify an Apache software, you are not allowed to call<br>
your modified software "Apache" (but you can said "based on Apache").<br>
The EPSG terms of use seems actually more flexible since it describe the<br>
changes that you are allowed to do and still keep the "EPSG" codespace.<br>
