Endings (voltas) and tied notes

[Mogens Lundholm]

Wanted to produce these notes (see attached jpg: Endings.jpg) with endings(voltas) and
tied notes into the endings. The other attached file: Endings.xml has <tie type="start"/>
in the first measure and <tie type="stop"/> in both measure 2 and 3.

This seems to me to be sane MusicXML.
But neither Finale (Songwriter 2012) nor MuseScore(2.0.3) accepts this construction.

Am I wrong? Is this not allowed?

Your MusicXML code is correct. Finale has some issues with importing MusicXML ties in this type of situation.

More endings: This example with volta+repeat seems to me to be totally insane.
Because entering Volta 2 with a repeat start will make the repeat number be 1. This
means measure 3 should not be played the first time.

However, I have the feeling that musicians might think otherwise. And both Finale
and Musescore plays measure 3 two times. Musescore does not save the MusicXML-file
right, but puts the <repeat ...> before the <ending ...>. While the DTD says:

<!ELEMENT barline (bar-style?, %editorial;, wavy-line?,
segno?, coda?, (fermata, fermata?)?, ending?, repeat?)>

This means that <ending ...> should before <repeat ...>. But Finale does it right.

Is the volta+repeat example insane? Or am I wrong? (Should I play measure 3, when entering volta 2)

More questions about sanity of MusicXML:

Nested repeats: I see no problem in writing two repeats at the same place in MusicXML.
The problem might be showing it in the notation program. (Used my creativity to show it -
both Finale and Musescore ignores the double repeats). See the attachment below:

The biggest collection of MusicXML files I have seen:
Karaosmanoğlu, M. K. (2012). A Turkish makam music symbolic database for
music information retrieval: SymbTr. Proc. Int. Society for Music Information
Retrieval (ISMIR).

There are 2200 files!
However in some of these song I found this: Is the following according to the
MusicXML DTD? What should be the meaning of it? (specifying rest and duration with no number)

This occurs in the song "hicaz--sarki--nimsofyan--sari_kurdelem--fahri_kayahan.xml"(Line 45):
<note>
<rest/>
<duration/>
<type/>
</note>

And
<accidental/>

I read the DTD as the PCDATA-element must be present:
<!ELEMENT duration (#PCDATA)>
<!ELEMENT accidental (#PCDATA)>

Does this make sense? Why specify duration with no number?

[Michael Good]

Durations need to be positive numbers to validate against the MusicXML XSD. That makam dataset unfortunately had a lot of MusicXML problems when it was first released. I don't recall if they have worked to fix those issues since then.
