You could know easily (about XML), as that is rather simple: that's a = standard serialization format.

Time to say there is something I miss in PDF: the ability to link to a = particular part of a document from the outside. HTML and the likes have = = identifiers (which can identify a part of a document) which you can link= = to using URL fragments (you know, the =E2=80=9C#any-identifier=E2=80=9D = at the end of some = URLs). As explained in another reply to this thread, I am seeking for a standar= d = convention, which could among other things, be used to write in comment = = and interpreted by IDE and editors, to link to others source files or = related documents. But if you cannot link directly to a particular part = of = a document, that is painful if ever the document is big enough. Think about the Ada reference, which is a rather big document. From time= = to time, you may see replies in this Usenet, with a link to a section of= = the standard, and many time to a particular point of a section. All thes= e = links are to HTML version of the reference. You cannot link this way to = a = PDF version of the standard, and that is what is missing to these format= s, = which I believe are better suited for printing than for what we could = expect in a computer environment. -- = Si les chats miaulent et font autant de vocalises bizarres, c=E2=80=99es= t pas pour = les chiens. =E2=80=9CI am fluent in ASCII=E2=80=9D [Warren 2010]
