Hello, Peter.<= br>
I've managed to speed up html generation from xml (make xslthtml) from = 32 min. (in my environment) to 4 min. by modifying slowest XSL templates. All my modifications incorporated in a single file stylesheet-xhtml-speedup= .xsl, which is included in stylesheet.xsl.
I performed optimization by analyzing output of:
xsltproc --profile --stringparam pg.version '9.6devel' stylesheet.x= sl postgres.xml

To make sure that result of the transformation is the same, I've compar= ed original .html's with .html's generated with modified templates.=
Unfortunately xslt generates random id's, so it's needed to exclude= them before comparing. I do that with:
for f in */*.html; do sed -e 's/id=3D\"\(ftn\.\)\?id[a-z][0-9]\+\&= quot;/id=3D\"id\"/g' -i $f ; sed -e 's/href=3D\"[^#]= *#\(ftn\.\)\?id[a-z][0-9]\+\"/href=3D\"#\"/g' -i $f; don= e


So if it's acceptable way to speed up generation of HTML (and maybe som= e other formats), what other steps should we take to move away from SGML? If the performance is still not satisfying, please let me know, I'll co= ntinue to optimize xslt.
Beside performance issues, I can see some difference in results of 'mak= e html' and 'make xslthtml'. For example, see doc/src/sgml/html= /spi.html (xslt-generated version doesn't contain the lists of function= s).

Best regards,
Alexander

I think this is great= result=C2=A0 and it's worth to start moving to xml.
=
I think that moving to XML is step backward, becaus= e XML is ugly.
I want to note, that it= 's 21-th century=C2=A0 and we should think about including pictures int= o our documentation, which will greatly improve it.
=
Yeah, +1.
XML makes = this easier.
And I think that= Lisp is much better for this =C2=A0puprose.
