4 Yacc/Bison grammar.

6 Build notes:
7
8 1. Bison 1.6 is known to crash on Win32 systems if YYINITDEPTH is too
9 small Compile with -DYYINITDEPTH=5000
10
11 2. This grammar has one shift/reduce conflict related to the use of a
12 class declaration with a base class (e.g. class Y : public X) and the
13 use of a maxOccurs (class Y :10). Internally the conflict is resolved
14 in favor of a shift by Bison/Yacc, which leads to the correct parsing
15 behavior. Therefore, the warning can be ignored. If this leads to an
16 error, then please enable the following directive (around line 121):
17
18 %expect 1 // Bison: ignore one shift/reduce conflict
