OWL 1.1 functional syntax quoting inside strings

string := '"' a Unicode string in normal form C '"'

How does one include a '"' inside a string? Are there any other  
characters that need special quoting, for example carriage returns?

Suppose, for example, I wish to include some xhtml as an XMLLiteral  
for a datatype property - are we sure this will work?

In the current OWLAPI abstract syntax parser, this is hopelessly  
broken...

Also, can we amend the spec to use curies[1] instead of qnames in the  
functional syntax, or simply some sensible abbreviation mechanism?
