Have we been following the HTML lang attribute for PG boilerplate
<https://www.pgdp.net/phpBB3/viewtopic.php?f=3&t=75903> thread at DP?
I enclosed the boilerplate in a <div lang='en'> on the few foreign-language
books I've repaired. As the thread pointed out it should not hurt to mark
all of the PG HTML boilerplates as lang='en'.
Cheers,
Rick
