Re: Docbook 5.x

Hello,

I measured following elapsed times on an Intel i5 processor:

1. generate all HTML files with dsl script (make html): 0:48 min.
2. generate all HTML files with xslt script (make xslthtml): 16:01 min.
3. generate all HTML files with xslt script in the new environment
(pure Docbook5): 4:07 min.
4. Generating different things via dsl scripts in the new environment
may be possible. But the changelog of the Docbook5 dsl scripts
shows, that the last modification occurred in 2004 - this way is a
dead end.

There is one principle and a lot of minor differences between 2 and 3.
Solution 2 is based on an xml-file and xslt scripts which are based on
Docbook4. The basic difference to 3 is, that in 3 everything is Docbook5
compliant: there are only Docbook5 xml- and xslt-files (as my workflow
is: db4 --> xml --> db5 -- (db5 xslt) --> html). The minor differences
concerns the fact, that actually there are errors in my xml files and
that I made only a few parameterisation to the Docbook5 standard xslt
files - no optimization at all.

I used following tools: perl, xmllint and xsltproc. osx and OpenJade are
obsolete in the new environment (so far, there is much more work to do).
