But it does vary:

<xsl:template match="question">
  <xsl:variable name="correct-answer"
    select="key('answers',@number)"/>
  <xsl:variable name="score"
    select="@weight * boolean(answer=$correct-answer)"/>
  ....
</xsl:template>

Every question gets a different score.

x + 1 = y

x is a "variable" depending on the value of y (and vice-versa), but given 
y, the value of x is fixed.

Udi's point about the "uninitiated" is well taken; but why should the 
language of BASIC or FORTRAN trump the language of mathematics?

Cheers,
Wendell
