In english, is browser performance well defined for cases like:
<H1> heading1 <P>
<H2> heading 2 <P>
<H3> heading 3 <P>
vs. (will this appear the same as)
<H1> heading1 <P> </H1>
<H2> heading 2 <P> </H2>
<H3> heading 3 <P> </H3>
even in the same browser? (MacMosaic is yes, MacWeb is no).
The HTML DTD does mention
<!ENTITY % stext -- as htext but also nested structure --
"P | HR | %list | DL | ADDRESS
| PRE | BLOCKQUOTE
| %literal | %htext">
but I have to admit to ignorance in reading BNF grammer,
such as in the DTD, correctly.
Your experience and advice is greatly appreciated.
