  Actually I believe it's NOTABUG, basically it's the result of fixing
    https://bugzilla.gnome.org/show_bug.cgi?id=587663

see http://www.w3.org/TR/2008/REC-xml-20081126/#AVNormalize
and libxml2 test case test/att10

 when you ask for entity susbtitution and that's the normal mode when
parsing a stylesheet to be compiled, the "&#xA;" coming from an entity
substitution will be replaced by as space, that's mandated by the spec,
and I missed that case previously.
 It's now fixed but also mean the stylesheet won't work as it used to.
The simplest is really to use &#xA; directly in the attribute value
c.f. the example.
