xsl:import assembles the stylesheet prior to execution. The stylesheet can't modify itself while it is executing, which is what you are trying to achieve.

If you have three variants of a stylesheet for use in different circumstances, represented by three modules A.xsl, B.xsl, and C.xsl, then instead of trying to import one of these into the module common.xsl that contains all the common code, you need to invert the structure: each of A.xsl, B.xsl, and C.xsl should import common.xsl, and you should select A.xsl, B.xsl, or C.xsl as the principal stylesheet module when initiating the transformation.
