BTW, I would have figured out how to write it in XPath1.0, but I thought that I must be missing something very obvious if I write lines of XPath for a supersimple "two-word" content model.

Although I would prefer (sorted by preference)

1. All of the below :)
Options are good IMHO.

2. Simple and short XPath match patterns for describing simple content models.

3. If external snippets are required, I'd prefer RNG over WXS, but ...

4. ... XSLT2+WXS might turn out to be an improvement over XSLT1 + very long XPaths.

Especially if the schema of the source of the transformation is written in WXS/RNG (the SVG WG might choose RNG for example), some situations might become quite fun: One could simply reference existing fragments of the XSD (~XPointers allowed?), and/or copy some others and use them as basis for the content model descriptions referenced in the XPath pattern (refernced as in your example above).

Awesome! I'm looking forward to your ideas.
