logical AND does not work in xsl:for-each element com

Hi xslt folks,

I know that the logical AND was surely discussed but it could not help me to
solve the problem.

Shortly I have teh following xml structure

<GEDCOM>
  <EventRec>
    <Participant>
      <Link Ref="X1"/>
      <Role>Y1</Role>
    </Participant>
    <Participant>
      <Link Ref="X2"/>
      <Role>Y2</Role>
    </Participant>
    <Participant>
      <Link Ref="X3"/>
      <Role>Y3</Role>
    </Participant>
    <Date>Date1</Date>
    <Place>Place1</Place>
    <Information>Info1</Information>
  </EventRec>

I want to locate a specific participant and extract the nodes Date, Place and
Info with the following xsl:for-each

<xsl:for-each select="/GEDCOM/EventRec/Participant[@Ref='X1' and
Role['Y1']]">
<xsl:value-of select="../Date"/>
</xsl:for-each>

The output for both cases separated is correct but when combined it displays
always 3 dates and not only one date

What I am doing wrong here ?
