Yes, it helped me a lot, thank you very much! After using XSL for some 
hours I was slightly going nuts probably... but now I came up with the 
following and it works as expected:

  <xsl:if test="marc:datafield[@tag=245]">
  <xsl:for-each select="marc:datafield[@tag=245]">
  <xsl:call-template name="subfieldSelect">
  <xsl:with-param name="codes">a</xsl:with-param>
  </xsl:call-template>
  <xsl:for-each select="marc:subfield[contains('n', @code)]">
  <span class="title_medium"><br/><xsl:apply-templates/></span>
  </xsl:for-each>
  <xsl:for-each select="marc:subfield[contains('p', @code)]">
  <span class="title_medium"><xsl:text> : 
</xsl:text><xsl:apply-templates/></span>
  </xsl:for-each>
  </xsl:for-each>
  </xsl:if>

Well... in fact this was just the part about showing MARC 245 using the 
original file "MARC21slim2OPACDetail.xsl" that didn't work as we wanted 
it. I have now replaced that part with the new one.
