I have a DTD file which has element like this
<!Element softpkg
(title
|author
|idl ?
|extension
)*>
in XML file I tried putting up idl tag twice and it validates
against the DTD.
This means if in Element definition, like in idl(we have ?) that
means the element can appear (if appears ) only once.
But element definiiton sofpkg says any element can appear, any
number of times. (has *)
Does this mean element idl can appear any number of times and is
valid??
or this is for any other element for which constraint is not
mentioned?
clear my doubts.
take care,
Shashank
