[MEI-L] figured bass and accidentials

[bohl at edirom.de]

Hi MEI-list,

I'm about to code some  passages of figured-bass and I don't know how to add
accidentials to the figures. Coding a note 'a' in the third octave with a
natural seven and a sharp third I only came as far as this:

<staff n="1">
    <layer>
        <harm staff="1" dur="4" tstamp="1" place="above">
            <!-- accidential: natural -->
            <num>7</num>
            <!--  accidential: sharp -->
            <num>3</num>
        </harm>
        <note pname="a" oct="4" dur="4"/>
    </layer>
</staff>

Can anyone help me replacing the comments with real data? And how could I
possibly code a slashed figure?

In MusicXML figured bass is much more elaborated concerning additions to the
figures, such as accidentals or slashes, see below:

<measure number="1">
    <figured-bass>
        <figure>
            <prefix>natural</prefix>
            <figure-number>7</figure-number>
        </figure>
        <figure>
            <prefix>sharp</prefix>
            <figure-number>3</figure-number>
        </figure>
        <duration>8</duration>
    </figured-bass>
    <note>
        <pitch>
            <step>A</step>
            <octave>3</octave>
        </pitch>
        <duration>8</duration>
    </note>
</measure>

Although I don't want to say MusicXML was the better schema for figured bass -
it is all but perfect - I wonder how its explicit portions could be transferred
to MEI.

In great expectation of discussion.
Sincerely,
Benjamin
