The DWARF V2 spec spells two attributes in two ways.
This proposal is that that the longer
spellings be adopted uniformly.

DW_TAG_template_type_param
(listed in Figure 1, page 7)
is spelled DW_TAG_template_type_parameter
in the body of the document (section 3.3.7, page 28).
SGI has adopted the spelling DW_TAG_template_type_param.

DW_TAG_template_value_param
(listed in Figure 1, page 7)
is spelled DW_TAG_template_value_parameter
in the body of the document (section 3.3.7, page 28).
SGI has adopted the spelling DW_TAG_template_value_parameter.

The choices SGI adopted are neither consistently
the longer nor the shorter name.
This inconsistency was an accident.

Editorial change:  Figure 1 should be corrected to show the spelling used in the body of the document.
