888	"""is-date"" should return ""true"" only if date parses cleanly"	erazlogo	simon	"right now ""is-date"" seems to return ""true"" if the field can be parsed into a valid date (regardless of what else it contains), which leads to the following loss of data when moving from the Zotero date field to CSL:

""1750-1754"" > ""1750""; 
""[2000?]"" > ""2000""; 
""ca. 2000"" > ""ca 2000""; 
""n.d."" > ""n.d""

All of the above should probably evaluate as ""false"" and just return the whole string."	enhancement	new	major		styles	1.5			bdarcus simon fbennett
