With a vertical gap, naturally.  See section 3.2 of Expert's guide.
Another possibility is to use a blank object, like Jeff suggested.

@DP is just a macro for //1v (or whatever @DisplayGap is) - so instead
of multiple @DP one can just use a single concatentation operator with
necesary amount of vertical space, e.g. //5v or //1i or whatever.

Nah!  See Albert's remarks above.  Lists need special @ListNewPage
instead of @NP because lists are structurally different.

@List symbol is recursively expanded into actual list entries on the
page, so to say.  @ListItem provides contents for those entries and
@EndList notifies the @List that recursion can be terminated as there
are no more items.

While @BL @LI @EL syntactically *looks* like enumeration in, say,
LaTeX - it's very different structurally.  @ListItem is a galley like
a footnote - it doesn't appear at it's invocation place, it travels to
some space @List allocated for it.

One can even contrive the following example (try it!):


    @PP This list outlines possible solutions to
    ``vertical gap'' problem.
    One can either use a concatenation
    operator @OneCol { @LI { "//" operator } }
    or an empty object.  @OneCol { @LI { empty object } }


    @PP That's all, folks.

So if one uses list, the gap (in Albert's example) or blank object (in
Jeff example) must be within @ListItem.  Using "gap" paramter to @List
is also possible but the gap will disappear at page boundaries.
