Looks like I didn't make myself clear. I don't want the
label prefix to be automatic.

I want the reference to automatically add "part ..." (in the
text) when the current part is different from the part of
the referenced thing.

I see that the example was too verbose to be minimal
enough. Second go:

"""
\starttext
\part{Part one}
\chapter[interest]{Chapter one}
\chapter{Chapter two}
As seen in \in chapter[interest]
\part{Part two}
\chapter{Chapter one of part two}
\chapter{Chapter two of part two}
As seen in \in chapter[interest]
\stoptext
"""

If you compile this example, you'll see that both \in's
print the same output, but the second one is referring to
chapter 2 in part 1, and this is not clear (it seems it's
referring to chapter 1 in the same part), so it should add
", part 1" to make it clear.
