The term 'direction' has two meanings, which is slightly confusing, I
admit: Either the `<direction>` MusicXML element or a 'direction' in
LilyPond speak, i.e., whether an object is positioned above or below a
staff (the latter is denoted by the `placement` attribute in
MusicXML).  Option `--nd` makes `musicxml2ly` ignore the `placement`
attribute.

The `<direction>` container covers a large group of musical symbols,
and omitting it completely is far too radical IMHO.  You have to be
more specific which subtypes (i.e., which `<direction-type>` elements)
should be ignored, and whether really a large group of files from
cpdl.org is affected by the problem you describe.

BTW, filtering out all `<direction> ... </direction>` blocks can be
easily done with a script containing a few lines of Perl or Python
code.
