Hi,

In the grammar of x3dv

http://www.web3d.org/x3d/specificat...02/grammar.html

the profile statement is defined as the following

profileStatement ::=
PROFILE profileNameId ;
profileNameId ::=
Id ;
....
Id ::=
IdFirstChar |
IdFirstChar IdRestChars ;
IdFirstChar ::=
Any ISO-10646 character encoded using UTF-8 except: 0x30-0x39, 0x0-0x20, 0x22, 0x23, 0x27, 0x2b, 0x2c, 0x2d, 0x2e, 0x5b, 0x5c, 0x5d, 0x7b, 0x7d, 0x7f ;
IdRestChars ::=
Any number of ISO-10646 characters except: 0x0-0x20, 0x22, 0x23, 0x27, 0x2c, 0x2e, 0x5b, 0x5c, 0x5d, 0x7b, 0x7d, 0x7f ;

This excludes the space character (" ", unicode 0x20) from possible
profileNameId's.

So what is the profileNameId of "MPEG-4 interactive" profile ?

It looks like, there is no real list of possible profileNameId's in the
X3D standard.

The list at

http://www.web3d.org/x3d/specificat...s.html#Profiles

and the matching links shows names "Core", "Interchange", "Interactive",
"Immersive" or "Full", but if you would trust this information, the
profileNameId of the MPEG-4 interactive profile would either be
"MPEG-4 interactive" or "MPEG-4 Interactive" which are both forbidden by
the "IdRestChars ::= Any number of ISO-10646 characters except: 0x0-0x20"
grammar rule cause of the space character.

So what is the name of the MPEG-4 interactive profile ?

"MPEG-4Interactive" ?
"MPEG-4interactive" ?
"MPEG-4_Interactive" ?
"MPEG-4_interactive" ?
"MPEG-4-Interactive" ?
"MPEG-4-interactive" ?
something different ?

Btw, is there still activ development of MPEG 4 players, that
support more than video, h.264 etc?
Envivio could display more than Quicktime, but the free WMP plugin
has gone (for whatever reason).
