Disbaled snapshot retrieval from non-local Maven repository.
jEuclid did not work out so far; still no MathML in PDF.
Added implicit conversion Angle => Double to simplify calculations.
Locations of DocBook files - and results of their processing - changed.
Found out that there is no support for Content MathML; had to switch to Presentation. Yuck!
Added a couple of literature references.
Switched to chunked HTML.
Still did not work out how to define entities in oXygen so that the locations of files are not hard-coded in DocBook...
