We know tags from other languages (Danish, English...). E.g. we have the tags " , ( and - . A piece of text surrounded by quotation marks could be a quote. A piece of text in parenthesis or dashes is a bit supplemental - like in my first sentence above. The speaking language has something like it, e.g. quotes are read with a different tone of voice. Notes are another example - there are tags to say, that a piece of music should be repeated, like the lines of "Frere Jacques". These tags start and stop very visibly, and affect what is between them.
In XHTML a tag will always begin with < and end with > - e.g. <body>. Apart from that, there's a few extra rules.
The tags should be correctly layered within each other - this corresponds to me not starting a quote within a paranthesis, and ending it outside of the paranthesis.
- all tags that start, should also end. In some cases the tag ends immediately.
- in correct XHTML the names of tags and attributes may only contain small letters. (But a value of an attribute may contain large letters - e.g. a link to the picture "myShip.gif".)
