German translation of loadable message list

I have built the latest version of Xerces-C++ 3.2.3 on Linux Ubuntu 
18.04 LTS and would like to translate the loadable message file 
"XMLErrList_EN_US.Xml" located under "src/xercesc/NLS/EN_US/" into German.

At the top of the XML file are some instructions which don't play well 
with German:

"(...)  - All messages start with a lower-case letter (except where
    a name is used as the first word) and do not have a period
    at the end."

Leaving a period (AKA "full stop") off of the string's end is OK. But 
German language uses upper-case initial letters for all nouns, not just 
words at the beginning of a sentence. Also, since many of the terms 
should be left in English which refer to XML names, these should be 
enclosed in single or double quotes since they are not German.

Is this a problem? I don't want to go to the trouble of creating 
translations for hundreds of strings only to discover that they cannot 
be used due to the way they are processed after being loaded.

(Or perhaps someone has already done this chore?)
