You can set the following options in the HTML set:

Output XHTML

Creates web pages meeting the XHTML standard on export. Choosing Output XHTML disables other output options that might conflict with this standard. Selecting this option automatically sets the Tags Case and Attribute Case options.

Tags Case

Specifies the capitalization for tags.

Attribute Case

Specifies the capitalization for attributes.

Indent

Specifies a method for indenting lines of code: using the authoring application’s tab settings, using a specified number of spaces, or using no indention.

Line Endings

Specifies a platform for line ending compatibility.

Encoding

Specifies a default character encoding for the web page.

Include Comments

Adds explanatory comments to the HTML code.

Always Add Alt Attribute

Adds the ALT attribute to IMG elements to comply with government web accessibility standards.

Always Quote Attributes

Places quotation marks around all tag attributes. Placing quotation marks around attributes is required for compatibility with certain early browsers and for strict HTML compliance. However, always quoting attributes is not recommended. Quotation marks are used when necessary to comply with most browsers if this option is deselected.

Close All Tags

Adds close tags for all HTML elements in the file for XHTML compliance.

Include Zero Margins On Body Tag

Removes default internal margins in a browser window. Adds marginwidth, marginheight, leftmargin, and topmargin tags with values of zero to the body tag.
