As you can imagine, we had some debates about this when we initially worked on XHTML-IM back in 2003-2004. Some people were in favor of a semantic approach, others in favor of a stylistic approach (these debates mirrored somewhat the similar debates in the W3C and the web community in general). I tend to agree now that the semantic approach makes more sense for use in IM, and you have explained the reasoning quite well. >> There is the matter of the <img/> tag that accepts a data:base64 >> as a src, leading to very big stanzas.

Usually something between 10k and 64k. But yes, there are restrictions, and I tend to agree that we should strongly prefer pointers to external images over inline data: URLs. > agree. possibly, we need to prefer XEP-231 for that? Probably. I'll look at the XEP in more detail and propose some text on this list.
