This is an XML Schema question not an XSLT question!

You can define the type of the element as a list data type that allows a
list of floats with minOccurs=0 and maxOccurs=1. Alternatively you could
define it as a union data type that's the union of a float and a zero-length
string.

You could also define the type as "nillable", but then you would have to
flag an empty element with xsi:nil="true"
