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.
