GERP constrained elements via DAS

It is now possible to get the GERP constrained elements via the DAS protocol. For instance the DAS command to get all the GERP elements on the BRCA2 gene (Human chr 13: 32889611-32973347) is:
http://www.ensembl.org/das/Homo_sapiens.GRCh37.constrained_element/features?segment=13:32889611,32973347

By default, you obtain both the constrained derived from our 16-way amniote alignments and the 33-way placental mammals ones (these include all the low-coverage genomes). You can filter the elements you want by using the argument type:
