In the SVG spec of 2000/03/03, section 4.3 reads:

"Elements in an SVG document fragment have an implicit drawing order, with
the first elements in the SVG document fragment getting "painted" first.
Subsequent elements are painted on top of previously painted elements."

However, section 4.5.1 reads:

"For certain types of shapes, marker symbols (...) can be drawn at
selected vertices. Each marker symbol is painted as if its graphical
content were expanded into the SVG document tree just  _above_  [my
emphasis added] the shape object which is using the given marker symbol
... The fill is painted first, then the stroke, and then the marker
symbols. "

This seems self-contradictory.  If a symbol is inserted above the shape
being rendered then, by rule 4.3, it will be rendered before the shape. 
However, the last quoted sentence in 4.5.1 indicates that the shape should
be rendered first and then the marker symbols.

Can you please clarify the intended meaning?
