Hi,
ISO seems to allow spaces among the digits of a binary literal, so as
to group them for readability, as in X'00ba b10c'. We seem not to.
(The B'...' form appears to be a PostgreSQL extension, but I imagine
if ISO had it, it would allow spaces too.)
Is it worthwhile to allow that? Or to add a compatibility note somewhere
around sql-syntax-bit-strings saying we don't allow it?
For comparison, byteain does allow grouping whitespace.
It seems that byteain allows arbitrary whitespace (tabs, newlines, etc.),
whereas ISO's X'...' allows exactly and only U+0020 space characters.
Whitespace for byteain must occur between digit pairs; spaces in X'...'
per ISO can be anywhere.
Regards,
