Out of ECMA-119 specification:
8.5 Supplementary Volume Descriptor
...
8.5.3 Volume Flags (BP 8):
The bits of this field shall be numbered from 0 to 7 starting with the least significant bit. This field shall specify certain characteristics of the volume as follows.
Bit 0:
if set to ZERO, shall mean that the Escape Sequences field specifies only escape sequences registered according to ISO 2735;
if set to ONE, shall mean that the Escape Sequences field specifies at least one escape sequence not registered according to ISO 2375.
On iso.org I found the ISO-2735 standard:
Hermetically sealed metal food containers -- Capacities and diameters of round open-top and vent hole cans for milk
And the ISO 2375 standard:
Data processing -- Procedure for registration of escape sequences
Could somebody confirm "ISO 2735" as a typing error meant "ISO 2375"? Is there an ECMA standard equivalent to ISO 2375?
Yes, I do believe you are correct in that there is a typographical error in Ecma-119. It should be Ecma-2375 where it says Ecma-2735. I will inform Ecma of this issue.
There is no Ecma equivalent to ISO 2375. However, ISO 2375 is referenced in some Ecma specifications, such as Ecma-35 (Character Code Structure and Extension Techniques).
