  I don't think it's what you actually have in your stylesheet.
but :
  <!ENTITY nbsp "<xsl:text disable-output-escaping='yes'>&amp;nbsp;</xsl:text>">

  otherwise your entity declaration makes no sense and libxslt would
not generate an error since there is no namespace used in the entity !

  that's theorically fine but if you do

  <foo xmlns:xsl="bar">&nbsp;</foo>
  <foo xmlns:xsl="err">&nbsp;</foo>

your &nbsp; reference would lead to different namespaces for the element
text and in 99% of the case you don't want this so my parser complain about
it.
Simply define the namespace in the entity:

  <!ENTITY nbsp "<xsl:text xmlns:xsl="..." disable-output-escaping='yes'>&amp;nbsp;</xsl:text>">

 then it becomes context insensitive and libxml2 won't complain.
Anyway using "disable-output-escaping" is bad practice in general...

  They are just a bunch of losers :-)
More seriously we have different appreciation of some of those suble issues.
