Ok.

In my case, there is no trouble with having `\document` and `\enddocument`
explicitly in the document, nor to add commands in preamble, as the
files are automatically generated and should only be run through tex4ht
scripts, never directly through TeX.

With this in preamble and the use of \document and \enddocument, 
the output is as intented, both the insertion of raw html and 
the formatting.  Thanks!


What would be the equivalent for httexi?  Is it the same?  


In httex the tex calls are like 

 tex  $5 '\def\Link#1.a.b.c.{\expandafter\def\csname tex4ht\endcsname{\expandafter\def\csname tex4ht\endcsname{#1,html}\input tex4ht.sty }}\def\HCode{\futurelet\HCode\HChar}\def\HChar{\ifx"\HCode\def\HCode"##1"{\Link##1}\expandafter\HCode\else\expandafter\Link\fi}\HCode '$2'.a.b.c.\input ' $1

In addition to calling etex, is that needed or should it be 
replaced by inlined plain-4ht.tex?

As a side note the tex calls in httexi are not exactly the same as in 
httex:

 tex  $5 '\def\Link#1.a.b.c.{\expandafter\def\csname tex4ht\endcsname{\expandafter\def\csname tex4ht\endcsname{#1,html}\input tex4ht.sty }}\def\HCode{\futurelet\HCode\HChar}\def\HChar{\ifx"\HCode\def\HCode"##1"{\Link##1}\expandafter\HCode\else\expandafter\Link\fi}\let\svrm=\rm\def\rm{\svrm\ifx\c\comment\def\rm{\let\rm=\svrm\catcode`\@=12\catcode`\\=0 \csname tex4ht\endcsname\catcode`\@=0\catcode`\\=13 }\expandafter\rm\fi}\HCode '$2'.a.b.c.\input ' $1


Thanks a lot in any case!
