RE: [ Revision #2 ] 15 elementary truths about XML
First, my +(N+1) on accepting all honest XML related posts on this list regardless of our opinion of them. I personally have enjoyed some of the side effects triggered by the questions Roger has raised in the past. I personally do not consider him a "Troll". A "Troll" is someone who maliciously intends to disrupt a list by feeding incisive or annoying commentary with the intent of annoying people or better yet incite others to annoy each other ('flame war'). Well enough of that ! Now for my own; I disagree with this slightly: >> 2. As noted above there are no characters in a computer, only bytes. Thus, "An XML document is a sequence of characters" actually means that an XML document is an abstraction >> of the underlying sequence of bytes. To me this implies XML has to be both A) On a computer B) In a text serialized form in bytes I'm actually not sure since I haven't reread the specs with this in mind but my opinion is that neither are requirements. A) If I print or write on paper or whiteboard "<XML/>" is that not still "XML" ? I don't expect a "XML Processor" to be able to read it, but is not "not XML" just because its in some other media ? And not represented by bytes and bits. B) There is a large body of practice where XML never ends up in text serialized form in 'bytes'. Not referring to Infoset or XDM. But rather in-memory "strings" of text serialized XML. Say a Java program dynamically creates an XML text message, in a Java String and parses it in memory. No where has it been converted to any encoding in bytes. Yet it is still "XM". So I would say more clearly "XML Is an abstraction of a sequence of characters" but not necessarily is there 'underlying bytes'. ---------------------------------------- David A.
