Seems that format-dateTime and format-time do not support precision smaller than seconds

Input:
format-dateTime(dateTime("2003-09-07T09:15:06.456"),"[H]:[m]:[s].[f1,1-1]")

Output:
⚠️ ️️here was an error.
 
Code: [FOFD1350] (this code can be looked up in the documentation and specifications).
 
Location information: file:/Users/mstevan/Documents/:LINE:1:COLUMN:0:
 
"[H]:[m]:[s].[f1,1-1]": a component specifier refers to components that are not available in the dateTime type

Expected output:
9:15:06.4
