import/include and apply-imports

strange behaviour using apply-imports

following example:

first.xsl:
------
<xsl:import href="third.xsl">
<xsl:include href="second.xsl">

second.xsl
--------
<template match="book">
  <xsl:apply-imports/>
</template>

third.xsl
------
<template match="book">
  AM I EVER EVER MATCHED?
</template>


the template in the third.xsl is NEVER matched!!
Why? I thought, that include means, the stylesheet is included like it was 
always in this file??

Is this correct behaviour? i am using Saxon and i dont think that saxon is 
making any mistakes, but including means to me just splitting a huge document.
