Situation:
Consider the following HTML5 document, which produces no warnings at https://validator.w3.org/nu/ (Tidy can properly handle most plausible warnings I could make it generate, but for the purpose of isolating variables, I made it not generate any):
<!DOCTYPE html><htmllang="en"><head><linkrel="stylesheet" href="https://fred-wang.github.io/mathml.css/mathml.css"><title>Circle equation</title></head><body><p>
The equation
<mathdisplay=inline><mi>y</mi><mo>=</mo><mo>±</mo><msqrt><msup><mi>r</mi><mn>2</mn></msup><mo>-</mo><msup><mi>x</mi><mn>2</mn></msup></msqrt></math>
produces a circle with radius <mathdisplay=inline><mi>r</mi></math>:
</p><svgwidth="10em" height="10em" viewBox="0 0 100 100"><desc>A circle</desc><circlecx="50" cy="50" r="40" fill="none" stroke="blue" stroke-width="1" />
</svg></body></html>
I ran this through tidy -asxhtml.
Expected result:
A valid XML document containing HTML, as described in the HTML spec. In particular, namespaces of the svg and math elements and their descendants should be accurate.
Actual result:
I get the two spurious warnings mentioned in #1046, but it also does not add the proper namespace directives to the math or svg elements. It adds a document-wide xmlns directive, but math and svg are not actually elements in the html namespace, so these are incorrect; it should add xmlns attributes to these as well.
Further note:
I expect both this and #1046 share the same cause; in particular, Tidy is trying to treat these elements as though the were HTML elements, which they are not.
