AlignmentML is a format containing (multiple) alignment information any alignment program like ClustalW can produce. Like in SequenceML different sequence types are supported. element contains alignment information with program data optional version tag type for alignment information with program information this element can contain program data represents an alignment sequences can be stored in this elements. at least two sequence elements are required optional score value for the alignment additional very specific information can be placed in unrestricted additional attributes represents a sequence in a sequence alignment name of the sequence synonyms for the sequence name a description can be placed here sequence data for aligned amino acid sequences sequence data for aligned nucleotide sequences sequence data for aligned unrestricted sequences a comment element required sequence identifier additional unrestricted attributes for specific needs A unrestricted sequence of chars, does not allow gaps An aligned nucleic acid sequence. TODO: Add this to Biotypes!
