/**
* xmp_model_parse_buffer:
* @xmp_model: pointer to the #XMPModel in which the results will be stored
* @buffer: buffer to be parsed
* @buffer_length: length of the @buffer
* @skip_other_data: if %TRUE, allow arbitrary data before XMP packet marker
* @error: return location for a #GError
*
* Parse a buffer containing XMP metadata and merge the parsed contents into
* the supplied @xmp_model. If @skip_other_data is %TRUE, then the parser
* will try to find the <?xpacket...?> marker in the buffer, skipping any
* unknown data found before it.
*
* (Note: this calls the functions from xmp_parse.c, which will call the
* functions in this file through the xmp_parser structure defined above.)
*
* Return value: %TRUE on success, %FALSE if an error was set
