tsd:alternate

This attribute can only have one of the following values:

• "shifted"
  The value "shifted" sorts words containing punctuation marks together (e.g. bi-weekly and biweekly), that is, punctuation is ignored for levels 1-3.

• "nonIgnorable"
  The value "nonIgnorable" (default) distinguishes these words and sorts them separately, that is, punctuation marks are considered to be significant.

Note:
This is the default root locale, i.e. the default collation attribute value according to the Unicode Collation Algorithm. However, this may be different if a specific language/locale is specified. For more information, refer to tsd:collation and to the collation documentation in the XML Schema User Guide.
