In FO31 19.3.6 Casting to list type,s, it is written:

"For example, given a user-defined type my:coordinates defined as a list of xs:integer with the facet <xs:length value="3"/>, the expression my:coordinates("2 -1") will return a sequence of two xs:integer values (2, -1), while the expression my:coordinates("1 2 3") will result in a dynamic error because the length of the list does not conform to the length facet. The expression my:coordinates("1.0 3.0") will also fail because the strings 1.0 and 3.0 are not in the lexical space of xs:integer."

With <xs:length value="3"/>, shouldn't my:coordinates("2 -1") fail and my:coordinates("1 2 3") succeed?  Note this also appears in F&O3.0.

It might be worth noting that in the minLength is 0, then my:list("") will return the empty sequence (or am I mistaken?)
