[Libreoffice] main.xdg 2 largest sections not needed on startup?

Hi all, after looking at kcachegrind for a while, I found that a
significant amount of our startuptime comes from allocating string
memory and comparing strings 400k times, much of it reading the
configuration files. I just looked at the .xcd files now and of that I
focused on main.xcd because this is likely to be read in on every app
start and is by far the biggest .xcd file.

Here is a breakdown of all xml sections with their LOC count (as
determined by xmllint --format). Each name has a component-data and a
component-scheme section it seems, I have not merged them. Anyway, the 2
biggest contenders are perhaps not even needed there.

File basis3.3/share/registry/main.xcd: total 63014 lines:

The 2 biggest sections are:
"Labels" 14345 + 11 lines (defining label sizes for printing envelope labels)
"TableWizard" 8666 + 26 lines

These make 1/3 of main.xdg, are both needed on startup or can those be
put into a different file that is only read when it is really needed?
