# What an interesting package! A bit complex to rewrite in Perl
# So, we'd prefer to just process the TeX source for it.
# Basically, we read in the TeX distribution's numprint
InputDefinitions('numprint', type => 'sty', noltxml => 1);
# That done, however, there are a few issues.
#  * numprint uses a mix of text & math modes to get the desired appearance.
#    Here, we'd like to try to be slightly semantic, so rewrap things.
#  * numprint uses a bit too much knowledge of latex's tabular
#    and latex's tabular doesn't quite match the internals of latexml's!
#======================================================================

#======================================================================
# (Pseudo) Semantics
#======================================================================
# When printing in text mode, wrap the number in something that _says_ that it's a number!
# And, avoid putting the various symbolic bits in Math mode (if we can)
# In Math mode, wrap it in an XMDual, and try to avoid parsing too much 'nonsense'.

# AND we need to tweak the scanner that looks for the end of the column
# (since ours end differently than normal LaTeX's)
#
# NOTE also that current browsers do not (yet) support the char:. alignment
# and that LaTeXML does not (yet) compute actual box dimensions.
# Thus (at the moment) these tabulars will not be aligned on the . Sigh!
# But maybe soon...?
