the curly-bracket notation can only be used in attributes that are defined
to be attribute-value-templates; the select attribute of xsl:value-of (and
all other attributes whose value is an expression) are not AVTs, so you
cannot use this mechanism.

Try:
>     <xsl:template match="element">
>	    <xsl:variable name="x" expr="@att2"/>
>         <xsl:value-of select="@att3"/>
>         <xsl:text> found </xsl:text>
>         <xsl:value-of select="//element[@att2=$x][2]/@att3"/>
>     </xsl:template>

I added the [2] because in your example you're looking for the second
element in which att2 has this value: I suspect this isn't quite right but
you haven't specified the problem in enough detail for me to do any better.

Alternatively, and probably more efficiently, use keys.
