Hi Riyafa,
I’m not completely sure what we are talking about. There are 2
options:
a) The construction of a data model instance in XQuery/JSONiq using the
functions (the fn: namespace should be implicit):
{
"boolean1": true(),
"boolean2": false()
}
This is an XQuery expression.
b) The serialization of a data model instance to a string (for output):
{
"boolean1": true,
"boolean2": false
}
This is a sequence of characters that is returned by the query
processor/serializer.
These are very close, but not the same and AFAIK that’s correct. To be
able
to process a) we need to get the XQuery parser right (and I think that
should already be the case) and to be able to produce b) we need to get
the
XMLSerializer right (and I don’t know if that’s already correct).
Does this make sense?
Which one are you concerned about?
Cheers,
Till
P.S. We have a similar situation for "null" and "js:null()".

Hi,
The object should be of the form:
{
"boolean1": true,
"boolean2": false
}
and not
{
"boolean1": fn:true,
"boolean2": fn:false
}
Any suggestions?
Thank you.
Yours sincerely,
Riyafa

In XQuery there are no boolean literals, but there are built-in
functions fn:true() and fn:false(). You could those for the tests.

Hi,
As I came to know now, boolean is not a LiteralType in the current
implementation. Am I to add it as a LiteralType and as a Literal()
in
grammar.jj as well? Boolean is not read in the grammar.jj file also.
Thank you.
Yours sincerely,

Hi,
I came across this issue when attempting to write test cases: I
tried
using boolean values in my object and it throws an exception. Also
it
throws the same exception when I try with only true or false
values:
