 /*! @file MsooXmlVmlReaderMethods.h
     @brief Collects MS VML parser code.
 
     Included by MsooXmlCommonReader.
     MS VML is not a part of the approved OOXML,
     it is described in ECMA-376 Part 4: "Transitional Migration Features".
     Required for interoperability in any version of MSOOXML.
     VML elements are referenced in ECMA-376 Part 1.
 
     All page numbers of the ECMA-376 documents refer to the 2nd edition.
