The xml_schema::buffer class is a simple wrapper for the raw data
buffer concept. Here is how you can use it:

char* data = ... // some data
size_t data_size = ... // number of bytes in data

xml_schema::buffer b (data, data_size); // 'b' now has a copy of data

char* p = b.data ();
size_t n = b.size ();

assert (n == data_size);
assert (memcmp (data, p, n) == 0);
