Oooh! A good time to trot out an Emerson quote:
A foolish consistency is the hobgoblin of little minds
There is an implicit proposal on the hypothetical table. It goes
While mixed XML content is strictly legal, it is likely to
reveal limitations of tools and libraries adopted by IVOA.
As such, no IVOA Recommendations will permit XML
- non-empty elements with attributes
- elements enclosing both sub-elements and literal values
Further, there appears to be a suggestion that numbers must be
written as attributes:
>> Why actually do we need that number right between the tags instead
>> of in an attribute?
so also forbid:
- non-string values, not written as attributes
If this is the proposal, I'll open the polling with a "no" vote.
Another word for "mixed" content is "flexible" content.
