:)

count(.|preceding-sibling::*)

instead then...?

The common misunderstanding likely comes from the default processing
inbuilt into XSLT, where position() will return a child's position
amongst its siblings.

It could maybe be split into 3 functions:

position() - the position of the node amongst the selected nodes to
process, as it is now

sibling-position() - the position of the node amongst its siblings

document-position() - the position of the node within the document

That would prevent any confusion...
