Please document the alternativeRestores context property, including its default setting. The default settings can lead to apparent bar-check failures when there are time signature changes in an \alternative block.
Thanks,
Holland

The default is: alternativeRestores = #'(measurePosition measureLength lastChord)

\version "2.19.49"

music =
\repeat volta 2 {
c1
}
\alternative {
{
\time 3/4
d2. |
\time 4/4
c1 |
}
{ d1 | }
}

<<
\relative c'' \music
\relative c' \music
