Unfortunately, I know from struggling with some fairly recent questions
that this doesn't work.  You can't use the document() function within the
'match' attribute of xsl:key.  Instead, define the key as if the input
document was the one with the keys in, at the top level of the stylesheet:

  <xsl:key name="mysetofkeys" match="/keybase/key" use="@name" />

Then, when you want to use it, put the key() function within an
xsl:for-each that has the document that holds the keys as its 'select'
attribute:

  <xsl:template match="keyref">
    <xsl:variable name="keyrefname" select="@name" />
    <xsl:for-each select="document('../shared/shared.xml')">
      <b><xsl:value-of select="key('mysetofkeys', $keyrefname)/ACRONYM" /></b>
    </xsl:for-each>
  </xsl:template>

This is kind of explained in the XSLT Recommendation at
http://www.w3.org/TR/xslt#function-key, right at the end of that section.

I hope that helps,
