sw XHTML export: <blockquote> can't have character children

Fixes the following reqif-xhtml validation error:

ERROR at 214: [XSD] cvc-complex-type.2.3: Element 'reqif-xhtml:blockquote' cannot have character [children], because the type's content type is element-only.

But this is probably useful in the general xhtml case as well.

[ Also add a way to not load a document when we want to cover "store"
behavior in a test. ]
