# The saxon:suppress-indentation attribute

When the output method is XML with `indent="yes"`, the `saxon:suppress-indentation` attribute may be used to suppress indentation for certain elements. The value is a whitespace-separated list of element names. The attribute follows the same conventions as `cdata-section-elements`: values specified in separate `xsl:output` or `xsl:result-document` elements are cumulative, and if the value is supplied programmatically via an API, or from the command line, then the element names are given in Clark notation, namely `{uri}local`. The effect of the attribute is to suppress indentation for the content of the specified elements, that is, no whitespace will be inserted within such elements, at any depth. The option is useful where elements contain mixed content in which whitespace is significant.
