Furthering the fix to #23, an empty value is added to an HTML select element when there is no default or fixed value specified.
This doesn't alter the existing behaviour that attributes with
@use="optional"provides an default, empty valueIf there is no
@use,@defaultor@fixedattributes a default, empty value is provided (this is a change)If
@use="required"is specified a default, empty value is still provided, so that the user has to make an informed choice, rather than the first item in the list being pre-selected and possibly submitted without even thinking about it. If the user tries to submit the form without chosing a valid (non-empty) selection then the HTML validation will complain.If
@defaultor@fixedis provided, no empty value will be provided. I think this is definitely correct for@fixed, but@defaultcould be argued that we should allow an empty value, but it shouldn't be the default. I did test this, but it is not what I am submitting because in my case my XML processor (that handles the submitted form) adds omitted attributes with their default value anyway. I don't mind adding this (a blank option when@defaultis set) if you think it is incorrect though.
