Buenas noches.
¿Me podéis aclara dónde puede estar el error aquí para xhtml?
------------------------------------------
Line 88, Column 5: invalid comment declaration: found delimiter "[" outside comment but inside comment declaration
<!--[if lte ie 7]>✉
Line 74, Column 1: comment declaration started here
<!--[if lte IE 6]> Line 88, Column 6: character data is not allowed here
<!--[if lte ie 7]>✉
You have used character data somewhere it is not permitted to appear. Mistakes that can cause this error include:
•putting text directly in the body of the document without wrapping it in a container element (such as a <p>aragraph</p>), or
•forgetting to quote an attribute value (where characters such as "%" and "/" are common, but cannot appear without surrounding quotes), or
•using XHTML-style self-closing tags (such as <meta ... />) in HTML 4.01 or earlier. To fix, remove the extra slash ('/') character. For more information about the reasons for this, see Empty elements in SGML, HTML, XML, and XHTML.
Line 90, Column 4: "endif" is not a reserved name
<![endif]-->
Lo más extraño es que he validado otra web igual y sin problemas.
¿Me podéis orientar sobre qué puede siegnificar?
Gracias.
