+OWNERS for third_party/libxml

It looks like libxml has to be updated, dominicc, looks like you did this last time, do you know if this can be done again?

Friendly ping.

Can anyone familiar with our libxml usage confirm whether this affects Chrome?
I tried to reproduce the original report but I could not reproduce it, see b/38332615#comment7

There's no upstream fix for this. I have doubts about a proposed patch, see https://bugzilla.gnome.org/show_bug.cgi?id=775200#c6

dominicc: friendly ping. This bug hasn't had any activity in several months. Do you know if an upstream fix is available now?

If it can't be reproduced or feasibly investigated please consider closing as WontFix. Thanks!

Joel, could you take a look?
Status: WontFix (was: Assigned)
I'm going to close this as WontFix.  I can't see that libxml has released any patch in relation to this issue, and since this issue we have rolled forward a number of times to the latest stable libxml release.
