About rdf:langString and form written representation

I apologize for a question related to RDF Schema. The Form class has a 
constraint on writtenRep which requires having at least one value with 
the rdf:langString datatype. As the language I'm facing with is a 
low-resourced language, there is no sublanguage tag in the IANA registry 
for it. So can I use writtenRep values with rdf:string datatype or it 
would be more appropriate using the "und" language tag?

Thanks in advance,

CL
