Example:

// If we configure compatibility options to comply with Microsoft Word 2003,
// inserting an image will define its shape using VML.

Assert.assertEquals(ShapeMarkupLanguage.VML, ((Shape) doc.getChild(NodeType.SHAPE, 0, true)).getMarkupLanguage());

// The "ISO/IEC 29500:2008" OOXML standard does not support VML shapes.
// If we set the "Compliance" property of the SaveOptions object to "OoxmlCompliance.Iso29500_2008_Strict",
// any document we save while passing this object will have to follow that standard.
