In all the examples of alternate geometry that I have seen, after 'objFile' is a 4-digit number. Is that always so?

Yes and No. The objFile must have a unique number so that Poser can monitor the alternative geometry so that it knows when to use it and what it is.

Numbers over 1001 are used as Poser uses some lesser numbers internally for other functions.

Does it have to be 4 digits - it usually is but I've seen 5 and 6 digit numbers used without Poser making a fuss.

The number is broken into two parts - a number for the body part and a number for the alternative geometry

the first two digits relate to a body part but it's not fixed, so 10 could be the hip, left shoulder or foot etc. Just keep it consistent so that all alternative hips would be 10, all alternative left shoulders would be 20, all alternative feet 30 etc etc

examples:

2001 would be left shoulder - alternative geometry 01

2002 would be left shoulder - alternative geometry 02

As to your other questions......

Can I set up alternate geometries from within Poser 11? > No - it still needs to be hand coded, or use one of the editor tools like Poser File Editor by d3d or the free Poser CR2 editor

Where is a full description of Poser 11 .CR2 file format including alternate-geometry matter? > I've never seen an official one released with Poser. Perhaps you could ask for a file breakdown over at the Smith Micro Official forum.

The CR2 file formate hasn't change much since the early versions of Poser and the best source of the internal file structure is still the very old "Secrets of Figure Creation With Poser 5" book by B L Render. other books that have some information : Practical Poser 7 or Practical Poser 8

Sadly many of the websites that had examples of the CR2 file structure vanished many, many years ago
