INTEGRATION: CWS xmlfilter02 (1.1.2); FILE ADDED

2007/05/10 15:50:14 hub 1.1.2.3: follow drr suggestion and use SAL_INT32_MAX instead of std::numeric_limits<>
2007/05/10 12:12:37 hub 1.1.2.2: Reviewed by: sj
Fix a 64-bits bugs: LONG_MIN and LONG_MAX were out of range for sal_Int32.
2006/02/14 18:40:16 cl 1.1.2.1: added initial libxml2 wrapper
