Assuming the context is:
EVENT[6]
And there are 10 EVENT elements.

Why am I getting different results for the following counts:

<xsl:value-of select="count(following-sibling::EVENT)"/>
<xsl:value-of select="count(following-sibling::node())"/>

Assume the following XML:

<ROOT>
  <EVENT />
  <EVENT />
  <EVENT />
  <EVENT />
  <EVENT />
  <EVENT />
  <EVENT />
  <EVENT />
  <EVENT />
  <EVENT />
</ROOT>
