[NTG-context] Bibliography: printing just Single Author et al.

[Mojca Miklavec]

Hi,

When citing articles with five authors I prefer to list all of them,
but in some articles with one hundred authors I would prefer just "J.
Someone et al." since listing five more co-authors doesn't add
anything substantial to the information.

Is there any trick that would allow liming the number of listed
authors on per-article basis? Simply specifying
    author = "Just Someone et al.",
?

(MkIV, experimental reimplementation.)

Thank you,
    Mojca
