Bugfix version OTDS 1.9.3 published

The OTDS association published the bugfix version 1.9.3, which practically is 100% downward compatible versus the latest version 1.9.2.

As common with bugfix-versions, mainly inaccurancies and minor errors were corrected in 18 „tickets“. Version 1.9.3 among other things improves the validation of some tags in relation to the Technical Specification. Impact conditions now may be used in filters as well. The issue of property processing, which in some cases was not always defined clearly, has been improved, whereas the IATA Airport Codes have been supplemented by Metropolitan Area Airport Codes. Also the Documentation has been corrected and complemented.
The new scheme files (XSD) and the change history can as always be downloaded for free within the OTDS-Forum.
