/*
 * QXmlName is conceptually identical to QPatternist::QName. The
 * difference is that the latter is elegant, powerful and fast.
 *
 * However, it is too powerful and too open and not at all designed
 * for being public. QXmlName, in contrast, is only a public marker,
 * that for instance uses a qint64 instead of qint32, such that we in
 * the future can use that, if needed.
