[CWB] Strange behaviour of /region[]?

[Thomas Proisl]

Hello everybody,

my name is Thomas Proisl, I'm a computational linguist from Erlangen and I'm 
new to the list ;o).

I have a question concerning the behaviour of the /region[] command. First a 
little bit of background information:

I have a corpus that consists of XML encoded files that validate against the 
following simple RNC schema:
start = element file {
      attribute name { xsd:ID },
      element s {
              attribute id { xsd:ID },
              attribute len { xsd:int},
              text
      }+
}

The corpus contains 6026213 sentences:
egrep -o '<s[^>]*>' * | wc -l
6026213

From what I've read in the manual, I expected
/region[s]
or
<s> []* </s>
to return all sentences. However:
A = /region[s];
size A;
6016995
A = <s> []* </s>;
size A;
6016995

cwb-s-decode on the other hand produces the expected number of 6026213 corpus 
positions:
cwb-s-decode TEST -S s | wc -l
6026213

Why does /region[s] return only 6016995 sentences? Is this normal behaviour?

Best regards
Thomas Proisl
