Re: xslt phases for FAQ, was Reading the XML declarat
It isn't clear if the sub headings below Phase 0, XML parse of stylesheet and input document: are intended to imply chronological order of those actions. If so the order is wrong but it's probably best not to imply any such order as in practice they are all interleaved. For example you have Expand character references and parsed entities; Determine source doc encoding. which clearly have to be done in the other order as far as the main document is concerned. Unless you know the document encoding you can't know that the bytes that look like "& a b c ;" do denote an ampersand an a, a b, a c and a semicolon, so denote a reference. External parsed entities each (can) have their own encoding declaration so you do have to determine the encodings used there after parsing (some of) the main document but before parsing the external entity. You have URI resolution (E.g. Catalog management) later in the list but clearly you can't expand external entities or discover what encoding they are in until you have resolved the URIs that refer to them. Basically I think you just need the last two items Build the internal model of the stylesheet (including URI resolution if needed) by parsing the stylesheet including any included or imported stylesheets. Build the internal model of the source document (if present) Action document properties such as xml:space, xml:base etc with a note that says that that involves some or all of the following actions in some possibly interleaved order, and then list your other items. In phase 1 you end with Build the output tree. but XSLT 1 and 2 are both written so that the output tree need not be built if it is going to be followed by stage 3. You can serialise as you go. This is why attribute nodes can not be added after any child elementnodes: so that you can serialse the start tag of teh parsent before serialising teh children, you never need to backup and add new attributes to the start tag of a parent.
