I have not, however, been producing valid xhtml. To do so, I need to remember to url encode my links, and also, apparently, a “blockquote” cannot appear inside a paragraph. I have to end the paragraph, start the blockquote, and then start a paragraph after ending the blockquote. The logic appears to be that the blockquote can contain paragraphs, so a paragraph cannot contain a blockquote. That sort of makes sense, I guess, but it is logically inconsistent, as, when writing, I generally continue the previous paragraph after the blockquote. This follows from years of highschool and college writing. Still, since in web pages I use a block format, not indenting my paragraphs, it visually produces the correct output this way, so it matters little.

According to feedvalidator.org, it seems that pretty much everything except some of the &s in urls and the <p> tags are acceptable. This pleases me, as the hack of including html when I should not was somewhat distressing. The sample is fairly representative, with some html entities, and some of the formatting tags I commonly use. So it seems I should look for something to replace my use of <p>, but I doubt I actually will.
