Consider this example:
\definelayer[extras]
[width=\paperwidth,
height=\paperheight]
\setlayer [extras] [x=2cm, y=5cm] {something}
\setupbackgrounds[page][background=extras]
This is ok, the placement is relative to the upper left edge of the
paper.
But following the Details manual, I should be able to use
\placelayer[extras]
instead of the background stuff.
But then the placement is relative to the upper left edge of the text
area.
Is this intended?

Another question, regarding layer placement:
\def\bleed{3mm}
\setvalue{LogoHeight}{20mm}
\setvalue{LogoWidth}{60mm}
\setvalue{LogoHOffset}{130mm}
\definelayer[logolayer]
[x=-\bleed, y=-\bleed,
width=\paperwidth, height=\paperheight]
\setlayerframed[logolayer]
[y=-\bleed, x=\dimexpr(\getvalue{LogoHOffset}+\bleed)]
[height=\dimexpr(\getvalue{LogoHeight}+\bleed),
width=\getvalue{LogoWidth},
frame=off, offset=0mm, align=low,
background=color, backgroundcolor=red]{my logo}
I would expect that the x/y coordinates in \setlayer(framed) relate
to the layer's origin (-3, -3) and thus my logo gets placed at (130,
-3).
But in fact it's placed at (133, -3), i.e. x starts at 0 instead of
-3. Why?

x and y are unique for each \setlayer, use hoffset/voffset instead

Thank you, I didn't understand that from the docs.
And in fact not even from your statement.
Seems like x/y always use the upper left corner of the paper,
while hoffset/voffset use the upper left corner of the layer.
But if I use \placelayer instead of backgrounds, x/y is relative to
the text area.
Is that intended? (See my mail "layer question".)

no, it depends on the combination of align and corner (in core-box.tex
you can see presets being defined, so with preset=rightbottom, x/y start
from the rightbottom)

indeed, put it in a \ruledhbox and you will see
(there is \tightlayer and such in order to get different results)
