nikolayo / xqgrammar Goto Github PK

W3C recommendation mandates that reserved names may not be used as function
names in unprefixed form. XQgrammar imposes the stronger restriction of
reserved names not being allowed for use as NCName at all. This is too
restrictive an unnecessary.

Rule for tumblingWindowClause should be :

tumblingWindowClause
    : TUMBLING WINDOW '$' varName typeDeclaration? IN exprSingle 
      windowStartCondition windowEndCondition?
    ;

What steps will reproduce the problem?
1. I invoked maven using the following command
   mvn -e -X clean install -l build.log
2.
3.

What is the expected output? What do you see instead?

The build script is producing two kinds of errors:
a. it looks like the maven plugins for antlr are not found
b. it also appears that there are errors in the grammar

What version of the product are you using? On what operating system?
See attached file.

Please provide any additional information below.
I also tried using antlrworks 1.4.3 and came up with the same grammar errors.

Besides syntax validity CharRef tokens must also be valid in the sence
of referencing a valid Char. This is checked by call to checkCharRef()
in the base class Parser. The grammar actions do that for hex CharRef
but not for decimal. There is also a bug in checkCharRef() for decimal
CharRef.
