Capitalization and proper nouns in references

[hfmark]

XML galleys inconsistently end up with proper nouns in titles lowercased. This doesn't happen with all articles, or with all references in an article (or all words in the title of a single reference). Example: for a recent paper, the reference in the bib file had
title = {Coseismic displacement field and slip distribution of the 2005 Kashmir earthquake from SAR amplitude image correlation and differential interferometry},
In XML the reference title became
Coseismic displacement field and slip distribution of the 2005 kashmir earthquake from SAR amplitude image correlation and differential interferometry
so, initial capital and SAR preserved, Kashmir not. In this particular paper most place names and months (eg october) were lowercased. In some places where articles had a "I" or "II" in the title as roman numerals, they were lowercased; in other places those were kept capitalized.

I don't really know which stage this is coming from or how to fix it but it's quite annoying. Extra brackets in bibtex don't seem to be the answer given that SAR was ok. Also this probably happens more often than I have noticed, and most HEs don't check (but Ake is more conscientious than most).
