Re: TRichView vs WPTools

I just passed a file saved by actiontest demo through W3C HTML validator.
It found the following incompatibilities:
1) There is no magic line
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
at the beginning of document
2) Charset is not defined (TRichView saves charset in HTML only if the 0-th
text style's charset is not a DEFAULT_CHARSET)
3) <img> misses alt tag (TRichView saves alt only if it is not empty; in any
case, you can provide it in OnWriteHyperlink event)
4) In tables, validator says that color values (like #FFFFFF) must be in
5) Validator does not understand that tables are contained in <P>. I tested
in browsers, well, it seems that only Internet Explorer understands it, so
this is really an incompatibility.
What's all. Do you really think these issues are really make HTML unusable?
In any case, thank you for pointing to this problem, I'll fix them in the
next update (1, 4, 5 and I'll think about 3)
"Simplified" HTML generates more warnings, but it was designed to be
compatible with old browsers. For example, it includes some tag attributes
specially for Netscape Navigator, and these attibutes produces validator's
But this HTML was specially created for compatibility with old HTML readers,
not with HTML validator.
