- Dan,
-
- You say HTML is not SGML. It is true that the HTML generted by the NeXT editor
- is not good. (example, lack of quotes around attributes which need them.)
- Hwoever, the current parser wil parse real SGML.
-
- I feel it IS important to keep the higher-level markup.
- Ypu ask, " Who really
- uses all the "format independent" features of WWW? I haven't seen
- anything that the RTF stylesheet features can't handle."
-
- Well, the line-mode browser uses these features to generate a particular
- style which is different from the Xwindows style. The LaTeX generation
- scripts which we use to make the "www book" use the high-level markup.
-
- It is true that HTML does not have a deep structure, so that we can
- be compatible with software whichcannot handle nested elements.
- There is nothing wrong with having a simple SGML DTD as a basic case.
- SGML does not HAVE to be complicated. You can use SGML to map any
- (non-overlapping) structure you like.
-
- In the future, the web will inclued more complex DTDs, and dynamically
- loaded DTDs, and people will want to use the same parser for it.
-
- You suggest that we should use RTF because it is better supported.
- Maybe we could use RTF in parallel in an experiment. Soe problems
- I have are that
-
- RTF uses a fudge of specially names styles to represent headings
- (for example, in Word) from which the WP deduces a structure
- (for outline mode, etc).
-
- RTF has styles, but as far as I could see Microsoft RTF documents
- have teh actuall formatting information always tucked in there even
- if it there is a style name attached.
-
- RTF has various extensions fopr handling for example embedded documents
- and links, but are these standard ized, or are different manufacturers
- going to use different tagsets in RTF just like SGML?
-
-
- Perhaps I am out of date in my knowledge of RTF (I certainly am).
- However, I see the WP manufacturers trying to escape from a position
- where they are historically bound to an RTF view, when they would like
- to be able to handle SGML.
-
- If you're talking about displaying things, to make HTML into RTF
- is trivial. You can make HTML into MIF too. You have to add
- style information of course. When you go back you have to do this
- fudge of requiring the same style names to be used.
-
- So I feel RTF would be a backward step. It is true that the current
- W3 software is at a point level with RTF rather than general SGML.
- But why tie ourselves to that point?
