Hi David,
Oxygen uses the Jing parser to validate XML documents with RNG/RNC
schemas so we present the messages as they are given by the parser.
I added an issue on the parser's GitHub issues list:
https://github.com/relaxng/jing-trang/issues/268
If you want you can provide more details on it, for example if you have
an idea about how the error message should be rephrased.
Regards,
Radu

Dear oxygen-user@oxygenxml.com,
I have a question about the error messages <oXygen/> reports when
validating a Relax NG rule that types an item as xsd:integer. My test
XML is:
<?xml version="1.0" encoding="UTF-8"?>
<?xml-model href="n.rnc" type="application/relax-ng-compact-syntax"?>
<stuff>1</stuff>
and my test Relax NG is:
start = stuff
stuff = element stuff { xsd:integer {minInclusive = "1"
maxInclusive = "1"} }
As I expected, both "1" and "01" pass validation. Initially I
(erroneously) expected "1.0" to pass because I thought validation
cared only about the value space, and not the lexical space, and it
didn't because I had misunderstood how integer was defined. Section
3.3.13 integer of https://www.w3.org/TR/xmlschema-2/ plainly says
"disallowing the trailing decimal point", a limitation of the lexical
space that automatically disallows the trailing zero.
I am, though, puzzled by the error message that <oXygen/> displays for
"1.0", which reads:
character content of element "stuff" invalid; must be a decimal
number without any significant digits after the decimal point
I think that the wording of the error message suggests that "1."
should pass, since the message seems to implies that the decimal point
is fine, and the mistake was putting a zero after it. Yet validating
"1." raises:
character content of element "stuff" invalid; must be an integer
This is consistent with the spec, as cited above, but also, I think,
misleading because the *value* of "1.0" is an integer, and the
prohibited trailing decimal point is about the lexical representation
of the value. The error message doesn't distinguish value space from
lexical space, although it could.
Am I alone in thinking that these two error messages could be clearer
because the error in both cases is the same: the lexical space of
xsd:integer does not permit a decimal point? Neither of these messages
fingers the decimal point as the invalid part of the content.
Sincerely,
David
