But, but, but, ... Why is space required between attributes? Surely 
a parser can recognize the start of the next attribute given the 
end-delimiter of the previous attribute's value, yes?



Because when XML was pulled together in the mid-1990's it was made to 
be an application of SGML from the early-1980's (retroactively 
modified a bit to accommodate some of the decisions made in XML).



Such a decision would have made an instance of XML not an instance of SGML.



And just because something is unambiguous doesn't make it meaningful 
to implement.



I hope this helps.

Hi Folks,



Is the following XML well-formed?



<altitude units="meters"reference="AGL">1000</altitude>



Scroll down to see the answer ...





















































No! It is not well-formed. There must be a space before 
reference="AGL" like so:



<altitude units="meters" reference="AGL">1000</altitude>
