My reading of [1] is that all lines must end with CRLF:

And in particular, for the component properties after BEGIN:VTODO, [1]
gives the general notation as:

> contentline   = name *(";" param ) ":" value CRLF

For example, the DTSTART notation [2] is:

>  dtstart    = "DTSTART" dtstparam ":" dtstval CRLF

And the same is true for all the other properties.
