    I hear that priority-tagged frames, i.e. frames having 0x8100 ethertype AND
    valan id equal to 0, are considered untagged from the VLAN-aware bridge
    perspective. however I could find exact wording on this in the standard
    802.1q-2005. Could anyone help me with this and point at the
    section/paragraph discussing this?

    Also, am I right that a vlan-aware bridge makes a decision whether teh frame
    is tagged or untagged, solely on TPID field value and doesn't take into
    consideration vlan id vallue (priority tagged frames are the only exception)
