This message may appear in several cases:
* You tried to include the "<" character in your page: you should escape it as "<"
* You used an unescaped ampersand "&": this may be valid in some contexts, but it is recommended to use "&", which is always safe.
* Another possibility is that you forgot to close quotes in a previous tag.

An entity reference was found in the document, but there is no reference by that name defined. Often this is caused by misspelling the reference name, unencoded ampersands, or by leaving off the trailing semicolon (. The most common cause of this error is unencoded ampersands in URLs as described by the WDG in "Ampersands in URLs".
Entity references start with an ampersand (&) and end with a semicolon (. If you want to use a literal ampersand in your document you must encode it as "&" (even inside URLs!). Be careful to end entity references with a semicolon or your entity reference may get interpreted in connection with the following text. Also keep in mind that named entity references are case-sensitive; &Aelig; and æ are different characters.
If this error appears in some markup generated by PHP's session handling code, this article has explanations and solutions to your problem.
Note that in most documents, errors related to entity references will trigger up to 5 separate messages from the Validator. Usually these will all disappear when the original problem is fixed.

This is usually a cascading error caused by a an undefined entity reference or use of an unencoded ampersand (&) in an URL or body text. See the previous message for further details.

If you meant to include an entity that starts with "&", then you should terminate it with ";". Another reason for this error message is that you inadvertently created an entity by failing to escape an "&" character just before this text.

This is generally the sign of an ampersand that was not properly escaped for inclusion in an attribute, in a href for example. You will need to escape all instances of '&' into '&'.

47. Error Line 160 column 47: the name and VI delimiter can be omitted from an attribute specification only if SHORTTAG YES is specified.
<option value="" selected>-</option>
"VI delimiter" is a technical term for the equal sign. This error message means that the name of an attribute and the equal sign cannot be omitted when specifying an attribute. A common cause for this error message is the use of "Attribute Minimization" in document types where it is not allowed, in XHTML for instance.
How to fix: For attributes such as compact, checked or selected, do not write e.g <option selected ... but rather <option selected="selected" ...
