[iso19139] multilingual, or option to prefer a language?

[pvgenuchten]

currently if you parse a document on Wasserspeicherfähigkeit, an object is returned with the german title, abstract. However the original document also has english translations for these fields. I would like an option to either store both, or prefer the english translation (if the document has it)

what is an optimal approach here?

• add a parameter preferLanguage=en to the owslib import, which locates a selected translation and returns default if no match
• try to store both, md.identifiation.title.{language}, for backwards compatibility, when users request md.identifiation.title the default language is returned
