Well, whether you have streaming or not supported, snapshot makes 
splitting up files where you want to preserve the tree structure easy e.g.

<xsl:for-each select="//foo!snapshot()">

B  <xsl:result-document href="foo{position()}.xml">

B B B B  <xsl:copy-of select="/"/>

B  </xsl:result-document>

</xsl:for-each>

Without snapshot in XSLT 2 you would need to write templates to 
reconstruct the ancestor tree of the foo elements. It is not that hard 
with the help of tunnel parameters but using snapshot for sure results 
in more compact code.
