[fitsbits] start of Public Comment Period on the INHERIT convention

[Lucio Chiappetti]

ANNOUNCEMENT:  START OF FORMAL PUBLIC COMMENT PERIOD

This is to announce the official start of a 3-week formal Public Comment 
Period on the incorporation of so called header inheritance (for short 
INHERIT) convention in the FITS Standard.

This is part of a process to incorporate the most useful, widely used 
registered, and simple conventions (which are valid FITS constructs) into 
the official definition of the standard.

This convention allows to specify whether keywords common to primary and 
extension HDUs can be written only once in the primary HDU and inherited 
by the extensions.

The proposed text consists just

- in the ADDITION of a several new paragraphs at the end of 4.4.2.6 after 
  blank keywords (hilighted in brick red colour)

   and has been prepared by a technical team including L.Chiappetti, 
   W.Pence, A.Dobrzycki, R.A.Shaw and W.Thompson (main editor 
   L.Chiappetti).

- If the proposal is approved a section H.3 will be added to Appendix H 
  describing the update, and the keyword will be listed in Appendix C

The proposed draft text is available at 
http://sax.iasf-milano.inaf.it/~lucio/FITS/Conventions/inherit-upd2.pdf
