Thanks Wolfgang for the quick answer.  I changed my code accordingly.
The "prefix=yes" option, though, does not entirely do as I expect it.
It adds the chapter+section number as a prefix to each theorem (and
lemma).  As I have "way=bychapter" in my options, though, it doesn't
reset after a new section started (which is what I want!). The effect
is odd as you can see in the minimal example.

I only want to have the chapter number as a prefix. It's probably
simple? difficult?

Minimal example:

~~~snip~~~
\setupenumerations
    [title=yes,
    style=normal,
    list=all,
    before={\blank[big]},
    after={\blank[big]},
    alternative=serried,
    width=broad,
    distance=0.5em,
    headstyle=bold,
    titlestyle=bold,
    way=bychapter,
    prefix=yes]

\defineenumeration
    [theorem]
    [text=Theorem, listtext={Theorem }]

\defineenumeration
    [lemma]
    [text=Lemma, listtext={Lemma }, counter=theorem]

\starttext
