CB: I talked to CSS team contact, who told me it will be on the telecon agenda.
... I will need to ping him again.
DP: EXI stream that use DTRM. in a way there is no types. Empty DTRM element in the header.
... Exificient parsed it correctly. The assumption is that there is no DTRM. Codec fallbacks to the default.
... The encoder expected differently.
... In Canonical EXI as well we say, if DTRM is empty, we can remove it.
... I am not sure spec is clear enough.
TK: We need a testcase in TTFMS.
DP: It seems that application/exi media-type is missing from IANA.
CB: I will contact liaison contact.
DP: I further tested. ZSTD from facebook and LZMA
... Both don't seem to beat Brotli.
... At least in default mode.
<caribou>https://www.w3.org/TR/WOFF2/ uses Brotli compression
DP: I looked into CSS.
... I tried some optimizations. I essentially changed the schema so that well-known CSS property names are enumerated.
... I tried to compare the result.
... This difference occurs if you can use strict and enumerated mode.
... We definitely need grammar strings.
... So that the structure is strict but content can be extended.
... I added ZSTD and LZMA in excel.
... I may be possible that those algorithms may work better with EXI.
... Once you use good algorithm like brotli, even EXI bytealigned almost works as good as precompression.
CB: WOFF2 requires brotli, and only brotli.

<caribou> IPR is clearly covered (https://datatracker.ietf.org/ipr/2396/)
DP: I was wondering, if it is useful to have a flag to assert there is grammar string is specified.
... For simplicity and performance.
... At "appinfo" level. To indicate the appinfo is for EXI.
TK: I will add it in section 3.
Our next telecon will be on January 10.
