=head1 NAME
Bio::EnsEMBL::Collection::Transcript - Feature collection implementation
for transcript features.
=head1 DESCRIPTION
=head2 Extended feature representation
A transcript is represented by the basic feature representation (see
documentation of Bio::EnsEMBL::Collection) and by the following extended
feature representation:
=over 4
=item 1.
Display label (display ID of the display Xref), if defined, otherwise
undef.
=item 2.
Biotype
=item 3.
Status
=item 4.
Is-current
=item 5.
Stable ID
=item 6.
Version
=item 7.
Created date
=item 8.
Modified date
=item 9.
Description
=item 10.
Confidence.
=item 11.
External name
=item 12.
External database name
=item 13.
External status
