sdaiCreateModelBNUnicode

This function creates and empty model (we expect with a schema file given).
Attributes repository and fileName will be ignored, they are their because of backward compatibility.
A handle to the model will be returned, or 0 in case something went wrong.

Property repository

Size: 64 bit / 8 byte (value)
Ignore this attribute, the value will be ignored in the current implementation, present for backwards compatibility.

Property fileName

Size: 64 bit / 8 byte (reference)
The file name of the file as available in the file system in Unicode (wchar_t *). The given wchar_t array will not be adjusted. The size of each wchar_t element is depending on the OS, both 16 bit / 2 bytes wchar_t elements as well as 32 bit / 4 byte wchar_t elements are recognized and supported.
