getUI5NodeFromXMLElementNamespace utility may return a too wide "namespace" type

[bd82]

The namespace property returned is a BaseUI5Node, Should it be a plain UI5Namespace instead?

  	/**
  	* Return the UI5 Namespace from the specified or default XML Element namespace
  	*
  	* @param xmlElement
  	* @param model
  	*/
  	export function getUI5NodeFromXMLElementNamespace(
  	xmlElement: XMLElement,
  	model: UI5SemanticModel
  	): {
  	namespace: BaseUI5Node | undefined;
  	isDefault: boolean;
  	isXmlnsDefined: boolean;
  	};

This is due to some possible edge cases that existed or may exist in the UI5 SDK.

• Some namespaces were mistakenly defined as an enum.
• In theory a UI5 Class may appear as a member of another UI5 Class (although no relevant instance is known).

Such a change may affect the behavior of some features, for example:

• Unknown namespace error in XMLView, how to treat a completely unknown namespace (foo.bar.x) versus a partially known but invalid namespace (sap.ui.core.x).
