Wrong "X axis" instead of "Y axis" in ODF 1.2 section 16.40.8

Hi,

the section "16.40.8 <draw:marker>" has the text

--- 8< ---
If the marker is referenced by a draw:marker-end attribute, the marker 
geometry is then rotated so that the X axis is aligned with the direction of 
the stroke in the end/start point direction. It is pointed to the stroke so 
that the origin of the coordinate system of the mapped marker geometry is 
positioned at the end point's position.
--- 8< ---

"X axis" here should be "Y axis", I assume.
At least this would match the draw:marker-start definition as well as what is 
implemented in LibreOffice and Calligra, from what I can see.

Cheers
