Notes and Potential Issues

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.

  1. Info 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.

  1. Error

    Sorry, I am unable to validate this document because on line 1 it contained one or more bytes that I cannot interpret as us-ascii (in other words, the bytes found are not valid values in the specified Character Encoding). Please check both the content of the file and the character encoding indication.

    The error was: Modification of a read-only value attempted
