Determines the default formatting style of the attribute names in trees. The available formats are bold, italic, underline, strikethrough, and hide. The fp:defaultattrnamestyle tag is the default value for all the trees (fp:tree) in the report. For each of the trees, you can override the default value by using the attrnamestyle="xxx" attribute of the fp:tree tag.
For quick reports, the default value (fp:defaultattrnamestyle) is always used, even if the report template contains fp:tree tags that have different attrnametyle values.
