could you please confirm that
count(tokenize( @Attribute,';'))
returns:
0 if Attribute=""
2 if Attribute=";"
Looking at http://www.w3.org/TR/xpath-functions/#func-tokenize it
clearly says
"If $input is the empty sequence, or if $input is the zero-length
string, the result is the empty sequence."
so yes, count(tokenize('', ';')) is 0.
And it also says
"If a separator occurs at the start of the $input string, the result
sequence will start with a zero-length string. Zero-length strings will
also occur in the result sequence if a separator occurs at the end of
the $input string, or if two adjacent substrings match the supplied
$pattern."
so you get 2 for count(tokenize(';', ';'))
