// Parser for HTML exportparts attribute. See
// http://drafts.csswg.org/css-shadow-parts/.
//
// Summary is that we are parsing a comma-separated list of part-mappings. A
// part mapping is a part name or 2 colon-separated part names. If any
// part-mapping is invalid, we ignore it and continue parsing after the next
// comma. Part names are delimited by space, comma or colon. Apart from that,
// whitespace is not significant.

// The states that can occur while parsing the part map and their transitions.
// A "+" indicates that this transition should consume the current character.  A
// "*" indicates that this is invalid input. In general invalid input causes us
// to reject the current mapping and returns us to searching for a comma.
