You're correct, this is not the advertising clause.
The advertising clause has the word "advertising" in it. Sorry.

I checked again and diffed the licence of Subversion 1.6.x to both the
Apache 1.0 and Apache 1.1 licences.
Apache 1.0 does have an advertising clause.
Apache 1.1 does not have an advertising clause, but has "strong
prohibitions on the use of Apache-related names" which is not
GPL-compatible according to http://www.gnu.org/licenses/license-list.html

The licence of Subversion 1.6 has equivalent "strong prohibitions on the
use of Tigris-related names".
So the FSF is still being inconsistent when they say that the licence of
Subversion 1.6 was compatible with the GPL. Not because of the advertising
clause, but because of the trademark protection provisions in the licence.

Thanks for correcting,
Stefan
