<!--
  This is the constraints template for users to define (1) constraint terms
  and (2) tuning architecture.

  The architecture can be divided into multiple audio features that a mobile
  device will support.

  1. Telephony
  2. Audio Output
  3. Audio Input
  4. Ambient Compute / Smart Features
  5. Others

  Also, the tuning architecture could be in reality treated as a tree like structure
  below and each node represents a triplet of (category, node name, constraint name).

  They'd be parsed into the logic behind the combobox drop down list dependent items.
  For more information, please check go/bluenote-uc-dd and go/blutenote-uc-treenote.

    id                The unique identifier for object or node.
    node              The reference node.
    tx-path           The transmit audio path.
    rx-path           The receive audio path.
    mixer-ref         The referenced mixer name.
