Ошибка Xerces-C при вводе двоеточия в корневое имя

Вот пример, основанный на образце Xerces CreateDOMDocument, в котором создаются только элементы в пространстве имен. Образец отлично работает для меня в Window 10, скомпилирован для бинарной версии xerces-c-3.1.1-x86-windows-vc-10.0:

Вывод в Windows с VS 2015:

The tree just created contains: 2 elements.
<?xml version="1.0" encoding="UTF-16" standalone="no" ?><svg:svg xmlns:svg="http://www.w3.org/2000/svg"><svg:circle/></svg:svg>

так что это работает нормально и не демонстрирует проблемы, о которой вы говорите, что сталкиваетесь со своими фрагментами.
