Latest News affecting IWXXM-US products

=======================================================================
Any changes to the schemas will be announced here in this file. In
addition, the GitHub website for the IWXXM-US UML model

https://github.com/NOAA-MDL/iwxxm-us-modelling

can provide advance notice of any upcoming changes to the schemas by
watching the Issues page at that URL.

Official notification of significant changes--which are greater than

will be announced on the NWS Service Change Notice page.

=======================================================================
Web site migration to a new machine was completed. The IWXXM-US schemas
have not changed but have been compressed into ZIP and GZIP files to
allow for easier downloads to your local machine. Included with the
compressed files, a sample OASIS Catalog file is provided to allow for
XML validation of IWXXM-US products using your local copy of the schema
files.

The upgrade of the server hosting these pages (as part of a much larger
web farm) has been postponed, now scheduled to occur beginning late 2023
into early 2024.

=======================================================================
IWXXM-US schemas metarSpeci.xsd and common.xsd versions changed from
3.0.1 to 3.0.2 to implement a bugfix.

 -- See https://github.com/NOAA-MDL/iwxxm-us-modelling/issues/5 for
    reasons why.

All other IWXXM-US schemas are essentially unchanged and remain at
version 3.0.0. Documentation blocks and elements' attributes have been
rearranged due to updates to Python 3.10 and the XML module
ElementTree which is used to get the IWXXM-US schemas in their final
form.

=======================================================================
There are plans to move these pages to a different, more modern and
better supported hosting system in Summer 2023. The transition will
likely result in these web pages being unavailable for a period of
time.

Web page outages, scheduled or otherwise, emphasizes the point to make
local copies of the schemas needed for XML validation purposes.
