XLL still supported?

[Edwin Knoppert]

MSDN lacks information for XLL excel addins severly.
The later MSDN has less info than previous MSDN libraries.

Can we say XLL addin's is (becomming) an obsolete technique?
I know my Excel version still accepts XLL addin's but if we as company want
to deliver such dll's my question is if this technique would remain for a
long period of time.

Thanks,

XLL Add-Ins still work in Excel 2003, and I suspect that they will in
future versions as well, but it is not the method that MS is
recommending now.

Yes, and that is my main concern.
I believe Excel is written around xll anyway internally, so removal seems
unlikely.
But they could exclude the addin part.
In msdn i seen xll topic being revisitted and updated to 2004.
They do not speak about removing the xll part.
