> A well-defined, valid and well-structured document makes it easier for

one to write <SPAN

CLASS="application"

|
|
For example you can use <SPAN
|
|
CLASS="application"
|
|
>XPath</SPAN
|
|
> to retrieve information in the
|
|
<TT
|
|
CLASS="sgmltag"
|
|
><sect3></TT
|
|
> block with certain attributes.
|
|
However if you just used <TT
|
|
CLASS="sgmltag"
|
|
><section></TT
|
|
> for all subsections,
|
|
it becomes harder to retrieve the block of information that you need.
|
|
</P
|
|
><P
|
|
> So which one should you use? The one you feel most
|
|
comfortable with is a good place to start. This document
|
|
is written with <TT
|
|
CLASS="sgmltag"
|
|
><section></TT
|
|
>s. You may,
|
|
or may not, think this is a good idea. :)
