Pretty sure this could be `<xsl:variable name="qualifier" select="normalize-space(@qualifier)"/>`... Could clean up some later logic...

Another note...  Should this Berkeley-specific date stuff be happening only in their mode?...  Not sure if it would really be a problem, but could the current date fields be in use anywhere?...  Might have to change to building up the prefix, if we do want to make it really "Berkeley-specific"...
