in user terms : MdC coding is easily understood and learned MdC coding is concise MdC coding provides two sets of functionalities :

basic (i.e. implemented by all rendering engines) extended functionalities (i.e. optional but implemented using a standardised

syntax) current MdC88 is supported for a certain period of time

In rendering engines terms : MdC coding is based on a « regular » syntax to be easily implementable and to reduce

the consumed resources software not supporting « extended functionalities » is silencious at rendering time Software should provide a tool signaling « deprecated » and not supported « extended

functionalities »

MdC88 fundation syntax is almost convenientanx wDA snb or G17 D54:I9 D21

MdC88 syntax for « modifications » is now inappropriate (chaotic, inconsistent)

usage and learning made difficult by needless inconsistencies

for instance ‘#’ for hashing and superposition

characters wasted mixing syntaxic and semantic roles

which character for aligments marks ?how to draw grey hieros ? $g ?

“irregular” syntax makes impossible to use standard tools

Deprecated : « marked as obsolete to warn against its use in the futureso that it may be phased out »

MdC88 fundation syntax is kept as it is

modifications of individual glyphs are always coded by postfixed operator beginning by a ‘/’

these operators may be factorised to several hieroglyphs by parenthesis

modification of « states » (orientation, direction,…) specified by # tags

MdC88 is fully supported (hopefully for a limited period of time)

A syntax checker is available

Suggested Road MapSuggested Road Map Define new syntax morphology guidelines.

As a consequence, list the « deprecated » syntax elements

List « Basic » functionalities (and associated syntax)

List a first set of « extended » functionalities (and associated syntax)

Determine appropriate milestones and associated timing

A dedicated working-group should be missioned and structuredto follow this road-map with a major milestone to the next I&E

meeting. An on-line forum should support this effort.
