The max value to 1 was introduced in 2c0a14d and then turned into a maxOccurs value in 6210296.

We can link multiple attachment (fonts) to a single track.

A track can reference multiple attachments.

The max value to 1 was introduced in 2c0a14d and then turned into a `maxOccurs` value in  6210296.

Fixes ietf-wg-cellar#930

As far as I can see, KaxTrackAttachmentLink has always been considered as unique in libmatroska. This change will introduce a behavior change there. cc @mbunkus

MKVToolNix doesn't use this element (as in, it doesn't write it). It can show it via mkvinfo, obviously, but that's it. Therefore changes to maxOccurs wouldn't affect me.
