The type xsd:NCName represents an XML non-colonized name, which is simply a name that does not contain colons. An xsd:NCName value must start with either a letter or underscore (_) and may contain only letters, digits, underscores (_), hyphens (-), and periods (.). This is equivalent to the Name type, except that colons are not permitted.

>>> musicxml.xmlObjects.isValidXSDID('hel_lo')

>>> musicxml.xmlObjects.isValidXSDID('4sad')
