function [supported, encapsulated, name] = dicom_supported_txfr_syntax(txfr_uid)
%DICOM_SUPPORTED_TXFR_SYNTAX Determine if a transfer syntax is supported.
% [TF, ENCAP, NAME] = DICOM_SUPPORTED_TXFR_SYNTAX(UID) uses the unique
% identifier UID of transfer syntax NAME to see if it is supported. If
% UID is supported TF has a value of 1; TF will be 0 otherwise. ENCAP
% is 1 if the syntax is used for uncapsulated data, which is usually
% compressed.
%
% If UID belongs to an unknown transfer syntax, TF is 0 and ENCAP is 1,
% as all native transfer syntaxes are specified.
