The following example demonstrates two problems with
alternative=margintext in \setuphead:
1. When used with start/stop sectioning, text following the title may
be set on the wrong line.
2. Without regard to the type of sectioning, margintext titles may
spill over the left edge of the margin and beyond the page frame.

This demonstrates two problems with
\type{alternative=margintext} in \tex{setuphead}:
\startitemize[packed,n]
\startitem
When used with start/stop sectioning, text following the
title may be set on the wrong line.
\stopitem
\startitem
Without regard to the type of sectioning, \type{margintext}
titles may spill over the left edge of the margin and beyond
the page frame. (Oddly, \tex{paperwidth} is less than the
sum of \tex{makeupwidth} and the margin widths and
distances for both letter and A4 paper.)
\stopitem
\stopitemize
\stopparagraph
\startparagraph
With start/stop sectioning, the text following the section
title may begin one line below the start of the title. That
can be remedied if there is no whitespace between paragraphs
with \type{insidesection={\blank[-line]}}, but the remedy
fails when there is whitespace, and increasing the correction
has no effect. With traditional sectioning, the text appears
baseline|-|aligned with the heading, as expected. The
the correction has no effect in any case with traditional
sectioning.
\stopparagraph
\startparagraph
It makes no difference in any test how the paragraphs are
delimited—blank lines, \tex{bpar}/\tex{epar},
\tex{startparagraph}/\tex{stopparagraph}, or \tex{par}.
