I was operating under the assumption that .property for an attribute would  
return to me the spec default value for that attribute if it was not  
filled in for some of my test cases...I'm realizing that can't really be  
accurate according to the letter of the spec, because all these varying  
min/max/step defaults for different INPUT types can not be enforced by the  
DTD since the INPUT element is so overloaded. The DTD can not express this  
complexity adequately to allow for the varying default values for these  

So - if I have
    <input type="datetime">
and request the field's .step property, is it ever possible to get "60"  
legally as a default return value, or would UAs need to "hardcode" these  
default values for each type?

Am I just missing something here?
