MapCSS text-offset implementation not compatible to MapCSS specification

Description
The description of the JOSM MapCSS implementation (https://josm.openstreetmap.de/wiki/Help/Styles/MapCSSImplementation) says that positive values for "text-offset" shift the text in upwards direction. But the MapCSS specification (http://wiki.openstreetmap.org/wiki/MapCSS/0.2) defines that positive values shift the text in downwards direction.
That means that the JOSM implementation is not compatible to the specification. So it is very difficult to use MapCSS stylesheets with different applications. Other tools like KothicJS or pgmapcss are compatible to the specification.

So in my opinion it's not too late for a harmonization.
Yes, however there are some more styles, see https://josm.openstreetmap.de/search?wiki=on&q=text-offset&page=1&noquickjump=1

how does Potlatch interpret the sign?)
Like in the specification.
Note that text-offset
is also used for text along line. There it moves the text in an upwards direction, which is the same in the specification, PL2 and JOSM implementation.
To change text-offset
for nodes, we can finally make use of @supports
. :)
node[amenity=library] { text-offset:10; } @supports (max-josm-version: 9999) { node[amenity=library] { text-offset:-10; } }
text-offset
/text-offset-y
is only used:So in my opinion it's not too late for a harmonization.
