[edit] Notes

• Using more than one fb:editor-date results in only the last date object being submitted in the postback.
• You need to validate the data this control provides as it can generate illegal date combinations such as February 31.
• If you post back to the same page, then the previous selection does not persist (appearing as if a validation error occurred).
• You cannot apply a name attribute to this tag; otherwise, no data is returned in the postback.
• If you need more than one date selector, use fb:editor-custom and insert the markup yourself.
