[lmi] Are XSL stylesheet DTDs imported?

[Greg Chicares]

Given that 'fo_common.xsl' declares an 'nbsp' entity, do other XSL files
that include it need to declare that entity in order to use it? See
'illustration_reg.xsl' as just one of several examples:

<!DOCTYPE stylesheet [
<!ENTITY nbsp "&#xA0;">
]>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; 
xmlns:fo="http://www.w3.org/1999/XSL/Format"; version="1.0">
  <xsl:import href="fo_common.xsl"/>
