For example, from intranet-tmpl/prog/en/xslt/MARC21slim2intranetResults.xsl the following string is pick up for translation: <xsl:with-param name="codes">abhfgknps</xsl:with-param> and it shows up as msgid "abhfgknps" There is no sense in "translating" that, it's just confusing for translators. It really should not be picked up for translation in the first place.
