It's not.  XPath says that "A / by itself selects the root node of the
document ***containing the context node.***"

The solution is to have a top-level variable pointing to the root of the
main document:

  <xsl:stylesheet>

  <xsl:variable name="main" select="/"/>

and then use

  sum($main//amount)
