Before XSLT processing can start, both the input XML and the
stylesheet have to be processed by the XML parser (get "parsed* into a
node-tree). It seems the parser cannot find the line

in first_stage.xsl, where it has found the entity. If you would
include it (or preemble.ent) at the beginning of your XSLT it would
parse.

Correct, the XSLT gets parsed first. The XSLT processor acts on the
node-tree, so it has done nothing up to that point.
