Having many extra elements (around 2000 more if you did this for MathML rather than XHTML) does cause some problems if you do wish to validate the document at any point using schema or dtd. Even if the end result is delivered as (just) well formed XML it is often useful to have a dtd to constrain authoring. Some drafts of MathML2 had a <mchar name="..."> element that had similar effect to this xmlchar proposal, but used a single element with an attribute. Docbook has a more or less similar uchar proposal. This has a much less drastic impact on a dtd (especially if the DTD doesn't constrain the name values) For these reasons mchar was removed from MathML2 at last call. It was understood that XML core WG would look at the problem. The "XML Core WG View" document being the rather unsatisfactory outcome....
