Without having the time to look at your code in depth: one thing that bit me recently was the fact that different characters have to be escaped in different vCard versions, so that you need to retrieve the version before you actually start to parse the value fields. > However, I believe we have the worst part of it behind us -- that is, > the line parser that splits individual lines into their component > parts: group, type-definition, parameters, and line-value (which may be > structured, repeated, or both).
