attributes
Name  Type  Use  Default  Fixed  Annotation
DEF  xs:ID        
appinfo

                    DEF defines a unique ID name for each node, referenceable by other nodes.
               
USE  xs:IDREF        
appinfo

                    USE means reuse an already DEF-ed node ID, excluding all child nodes and all other attributes (except for containerField, which can have a different value).
               
class  xs:NMTOKENS        
appinfo

                    The class attribute is a space-separated list of classes, reserved for use by Cascading Style Sheets (CSS) and XML stylesheets.
                    This attribute is only functional if the X3D model is loaded within an HTML page.
               
id  xs:NMTOKEN        
appinfo

                    The id attribute is a unique identifier, reserved for use by HTML5/DOM pages, independent of DEF labeling and internal X3D node referencing.
                    This attribute is only functional if the X3D model is loaded within an HTML page.
               
style  SFString        
appinfo

                    The style attribute provides an inline block of CSS for element styling, reserved for use by Cascading Style Sheets (CSS) and XML stylesheets.
                    This attribute is only functional if the X3D model is loaded within an HTML page.

provide inputs to parent (X3DSoundChannelNode, X3DSoundDestinationNode, X3DSoundProcessingNode) as part of audio graph, otherwise standalone as childe in scene graph
enumeration outputs
appinfo
parent node is ChannelSplitter, which is providing single-channel signal input to this node
enumeration source
appinfo
parent node is Sound node: legacy X3D3 SFNode source is allowed content model (AudioClip or MovieTexture only), prefer X3D4 MFNode children.
