According to [the spec](https://datatracker.ietf.org/doc/html/rfc6350#section-6.4.1), the line `TEL;TYPE="work,fax";PREF=1:+45 1234 1234` is a valid result to represent _"type parameter values specified as a parameter list (e.g., TYPE=text;TYPE=voice) or as a list (e.g., TYPE="text,voice")"_. However, [vcard4-ts](https://github.com/MarcelWaldvogel/vcard4-ts) logs this nag: ```JSON { "key":"PARAM_UNESCAPED_COMMA", "description": "Unescaped comma in parameter value", "isError": false, "attributes": { "property": "TEL", "parameter": "TYPE", "line": "TEL;TYPE=\"work,fax\";PREF=1:+45 1234 1234" } } ``` Am I misunderstanding something, or can I safely ignore this nag?
