so you are adding the space, not the xslt system.

In an xml attribute the xml parser will normalise newlines to a space so
you are adding  9 spaces before each key of the map from a newline and 8
spaces.
You could replace . in replace(.,'''','')  by  normalize-space(.) or
replace(.,' ','') depending how aggressively you want to remove space.
