The following notes and warnings highlight missing or conflicting information which caused the validator to perform some guesswork prior to validation, or other things affecting the output below. If the guess or fallback is incorrect, it could make validation results entirely incoherent. It is highly recommended to check these potential issues, and, if necessary, fix them and re-validate the document.
No Character encoding declared at document level
No character encoding information was found within the document, either in an HTML meta element or an XML declaration. It is often recommended to declare the character encoding in the document itself, especially if there is a chance that the document will be read from or saved to disk, CD, etc.
See this tutorial on character encoding for techniques and explanations.
Below is a list of the warning message(s) produced when checking your document.

Column 79:

The document located at <https://upload.wikimedia.org/wikipedia/commons/2/28/Flag_of_New_Hampshire.svg> was successfully checked as SVG 1.1 + URL + HTML + MathML 3.0. This means that the resource in question identified itself as "SVG 1.1 + URL + HTML + MathML 3.0" and that we successfully performed a formal validation of it. The parser implementations we used for this check are based on Compound XML and libxml2 (XML).
If you would like to create a link to this page (i.e., this validation result) to make it easier to revalidate this page in the future or to allow others to validate your page, the URI is <https://trans.hiragana.jp/markup/check?uri=https%3A%2F%2Fupload.wikimedia.org%2Fwikipedia%2Fcommons%2F2%2F28%2FFlag_of_New_Hampshire.svg;ss=1> (or you can just add the current page to your bookmarks or hotlist).
If you use CSS in your document, you can check it using the W3C CSS Validation Service.
