For anyone following closely, I should probably clarify that the 
stylesheet I'm talking about above is not the same stylesheet I posted 
earlier, which was just a toy example.  Of course, they both use the same

Thanks for doing this.  This is good to know.

Could you clarify one point? My use of the word `expected' in the original 
post was a bad precedent as it's ambiguous. I gave two sets of output 
produced by libxslt: (1) the desired output, which is produced when 
`keyAnotB' comes before `keyB', and (2) some undesired output, which is 
produced when `keyAnotB' comes after `keyB'.  Did you happen to try both?  
Are you saying the output always agreed with libxslt or was always the 
desired output?

Thanks for the suggestion. I will pursue this.
