xsl:copy makes a shallow copy of a node, and, by definition, a copy is
identical to the original.  Instead, use the xsl:attribute instruction to
create a new attribute with the same name, but with the new value:

  <xsl:template match="@myAtt">
    <xsl:attribute name="myAtt">hi there</xsl:attribute>
  </xsl:template>
