Future work will focus on increasing the coverage of the grammars, as well as the number of alternative options explored.
both approaches for auxiliaries should be compared using alternative analyses for verb-second word order found in other HPSG-based grammars, such as the GG (Müller and Kasper, 2000;Crysmann, 2005), Grammix (Müller, 2009;Müller, 2008) and Cheetah (Cramer and Zhang, 2009) for German, and Alpino (Bouma et al., 2001) for Dutch.
