ODA (Office Document Architecture) provides a standard for
document interchange (Office Document Interchange Format,
ODIF). The ODIF may in a sense be seen as a pendant of the
tag format as defined by the SGML declarations part. The
way raster or geometric graphics and character contents are
exchanged in ODA is not part of the SGML standard, as the
interpretation of such data parts are left to the
application. It is however likely that such 'content
portions' will be standardized under SGML in the near
future. In the area of content descriptions ODA standards
may be merged into an 'extended SGML'.
Do you think this is a correct statement?
