  Okay I think I realized what is confusing you. In the new callback
the attributes values are not copied in a new zero terminated string,
rather pointers to the beginning and the end of the attribute value are 
given, this potentally avoids an awful lot of allocations/deallocations,
most of the time those are direct pointer from the UTF8 document stream.
The pointer to the routine in SAX2 should be relatively clear about this.
It's also documented in
  http://xmlsoft.org/html/libxml-SAX2.html#xmlSAX2StartElementNs
  attributes:   pointer to the array of (localname/prefix/URI/value/end) attribute values.

  so the array contains 5 pointer per attribute found
