--------------------------------------------------------------
With PR #155 and #156 we have the complete set except the 3 date/time
formatters : fn:format-dateTime etc.
Unless I'm missing something, Java8 does not include code to implement the
picture format defined in Xpath/Xquery Functions and Operators. So, even for
just the ISO 8601 calendar, it's a significant piece of implementation.
See https://www.w3.org/TR/xpath-functions-3/#rules-for-datetime-formatting
Examples (from F&O 3.1):
{noformat}
2002-12-31 format-date($d, "[Y0001]-[M01]-[D01]")
12-31-2002 format-date($d, "[M]-[D]-[Y]")
31-12-2002 format-date($d, "[D]-[M]-[Y]")
31 XII 2002 format-date($d, "[D1] [MI] [Y]")
{noformat}
(Saxon-HE may have the code : it is Mozilla Public License which is category B
/ weak copyleft)
Jena provides {{afn:sprintf}} and that has some date/time formatting
capabilities and a picture format that users wil probably expect.
Therefore, I propose we close this JIRA with many thanks to ales004 for his
contributions.
