I suppose ... I guess I see the problem as a lexical issue and not an 
algorithmic issue.  I cannot comment on optimization opportunities 
for XSLT engines when faced with an explicit string or a variable 
reference ... perhaps someone on the list can comment on this.
Would you tackle the following with a variable as well?

<!DOCTYPE xsl:stylesheet [
   <!ENTITY nbsp '&#xa0;'>
]>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
                 version="1.0">

 . . . . . &nbsp; . . . . .

I don't think people new to XSLT should forget that we are, after 
all, working with XML files.
