In this case the first result is correct given the XML example. There are
three cases where
      <CHARACTER_ID> 10010 </CHARACTER_ID>
      <CHARACTER_STATUS> 6 </CHARACTER_STATUS>

are used. So the instruction,

	<xsl:value-of select="concat('STATUS ',CHARACTER_STATUS,
                                   '  ',count(key('kByID',CHARACTER_ID)),
                                   $NL)"/>

Generates 'STATUS 6 3' because key(..) returns a nodeset of these three
elements. The <xsl:if ..> is actually redundant since vUniqueCharacters does
not contain any duplicates.

On the second stylesheet you are referring to a MESSAGE attribute which does
not exist in the XML document. There is an element by that name but I can't
see how it is relevant to your stated goal of counting messages where
TARGET_CHARACTER_LOCATION_ID != LOCATION_ID

Try replacing your vNumNotSame by this and it should fix the problem,

<xsl:variable name="vNumNotSame"
select="count(LOG/*[number(TARGET_CHARACTER_LOCATION_ID) !=
number(LOCATION_ID)])"/>

I have used number() here to force number comparison otherwise you get
string comparisons which may or may not work depending on formatting.
