Fix Query Grammar

[sebbader-sap]

What happens?

Bug fix needed for security and query in grammar:

<ws> ::= ( " " | "\t" | "\r" | "\n" )+
<idShortPath> ::= ( <idShort> ("[" ( [0-9]* ) "]" ) ( "." <idShortPath> )* )

Why is this wrong?

No space etc. should be allowed as well.

How should it be fixed?

<ws> ::= ( " " | "\t" | "\r" | "\n" )*
<idShortPath> ::= ( <idShort> ("[" ( [0-9]* ) "]" )* ( "." <idShortPath> )* )

This doesn't address all the issues. In many cases, whitespace should not be permitted at all.
For example:
<year> ::= <digit> <ws> <digit> <ws> <digit> <ws> <digit> <ws>
There should be no spaces in the year.
