Yes. Exactly.
We are targeting this at transcribers, not blind readers who need software
to determine some small equation that might be math.

So are you proposing that the transcriber insert it as math and that
liblouis assume that if it isn't marked as math, then it isn't math? I
think this would be better than compromising good braille by trying to fix
up bad files.

Not computer Braille. Braille Formats has Nemeth-like symbols for plus signs
and equal signs when they appear in literary text. But something like pi
equals 3 point one four should be transcribed in Nemeth code. In my opinion
anything that is expected to come out in Nemeth code should be enclosed in
MathML. The transcriber should be able to handle this.
IMHO

Back translation of braille will always have ambiguities. I do not believe
that forward translation should be compromized in order to make back
translation occasionally better.
I have another question. Why should something not within math tags be
translated as math braille? I was under the impression that expressions
containing non-literary symbols such as = or + should be translated as
computer braille. Is there a rule? Mike?

After it has parsed and interpreted a MathML expression liblouisxml calls
liblouis with a special math table to do the final translation.
For Nemeth, this table is nemeth.ctb. It uses the include opcode to read
another table called nemethdefs.cti. This table then includes the
character-definitions table chardefs.cti. This may be one source of
confusion. Perhaps nemethdefs.cti should contain all character definitions
and leave the literary character-definitions table, chardefs.cti, to go its
own way. However, the line between literary and math can be blurry. For
example, a popular magazine article might contain the equation pi=3.14159,
not enclosed in MathML but simply part of qe text. So the literary
character-definition table must define symbols like = as math to get good
translation and back-translation.
