I had to look it up, myself. Actually the reference is correct, while the 
usage in the vast majority of plugins is incorrect. Effectively, no type filter 
is applied in all those varslots.

That said, I'm not too sure, whether it would be a good idea to go about and 
fix the plugins, right away. I fear the concept may be too strict in some 
cases, and probably isn't too self-evident (the varslot will simply refuse to 
accept objects not matching the filter). Perhaps it would be a better idea to 
allow the user to select any object they like, but instead to give some sort 
of visual indication, that this could be a problem (like a small warning sign 
next to the variable name, with an appropriate tool tip). What does everybody 
else think about this? How strict should we be in "protecting" the user from 
selecting a wrong type of data?

Note: Essentially the same consideration applies to the classes="" attribute, 
which is used much less frequently, however.

Regards
Thomas
