Also, one can pass multiple references as in:

\startchapter[reference={foo,bar},...]

Anyhow, as an experiment I've added a space stripper to the 'definition' 
part of references

\starttext

\startsection [title=Test 1, reference=ref 1]              \stopsection
\startsection [title=Test 2, reference={ref 2}]            \stopsection
\startsection [title=Test 3, reference= {ref 3}]           \stopsection
\startsection [title=Test 4, reference={ref 4} ]           \stopsection
\startsection [title=Test 5, reference= {ref 5} ]          \stopsection
\startsection [title=Test 6, reference={ ref 6 , ref 7 }] \stopsection

\dorecurse{7}{
     \in{ref}[ref #1]
     \in{ref}[ ref #1]
     \in{ref}[ref #1 ]
     \in{ref}[ ref #1 ]
     \par
}

\stoptext

This all works ok but someone needs to document it at the wiki. Of 
course one can come up with yet another 'wanted tolerance' but we 
shouldn't become to fuzzy.
