"or alternatively can be indicated as properties on elements"

[kba]

Language and writing direction should be indicated using the HTML standard
attributes lang= and dir=, or alternatively can be indicated as properties on
elements.

Not clear what that last clause means. Title properties dir and lang?

I would delete it, one standard mechanism for dir/lang is better.

👍 This looks also more conform with what is written somewhere else:

• "all writing direction changes must be indicated with tags." http://kba.github.io/hocr-spec/1.2/#hyphenation
• "ocrp_dir: Capable of generating dir= attributes" http://kba.github.io/hocr-spec/1.2/#capabilities
