Phylogenetic data (i.e. evolutionary trees and the data they are based on) is commonly stored in the NEXUS flat text file format. Unfortunately, this format is fairly difficult to parse due to incompatible "dialects" that have evolved over time. Also, a formal means to validate all flavors of NEXUS does not exist. Several XML formats to replace NEXUS have been proposed, none of which, for practical and historical reasons, have been widely adopted. One reason why none of these efforts have been successful is that they never sought to integrate the proposed format with existing bioinformatics toolkits and the objects they define. We are therefore working design an XML format that:
can express (at least the biological data part of) the NEXUS specification,
can be validated using DTD or XML schema,
is flexible enough to allow adding further annotations (e.g. a key/value system for taxa and sequences),
is optim
