=head1 NAME
-SQL::Translator::Producer::XML - XML output
-
-=head1 SYNOPSIS
-
- use SQL::Translator::Producer::XML;
+SQL::Translator::Producer::XML - Alias to XML::SQLFairy producer
=head1 DESCRIPTION
-Meant to create some sort of usable XML output.
-
-=head1 ARGS
-
-Takes the following optional C<producer_args>:
-
-=over 4
-
-=item emit_empty_tags
-
-If this is set to a true value, then tags corresponding to value-less
-elements will be emitted. For example, take this schema:
-
- CREATE TABLE random (
- id int auto_increment PRIMARY KEY,
- foo varchar(255) not null default '',
- updated timestamp
- );
-
-With C<emit_empty_tags> = 1, this will be dumped with XML similar to:
-
- <table>
- <name>random</name>
- <order>1</order>
- <fields>
- <field>
- <is_auto_inc>1</is_auto_inc>
- <list></list>
- <is_primary_key>1</is_primary_key>
- <data_type>int</data_type>
- <name>id</name>
- <constraints></constraints>
- <null>1</null>
- <order>1</order>
- <size></size>
- <type>field</type>
- </field>
+Previous versions of SQL::Translator included an XML producer, but the
+namespace has since been further subdivided. Therefore, this module is
+now just an alias to the XML::SQLFairy producer.
-With C<emit_empty_tags> = 0, you'd get:
+=head1 SEE ALSO
- <table>
- <name>random</name>
- <order>1</order>
- <fields>
- <field>
- <is_auto_inc>1</is_auto_inc>
- <is_primary_key>1</is_primary_key>
- <data_type>int</data_type>
- <name>id</name>
- <null>1</null>
- <order>1</order>
- <type>field</type>
- </field>
+SQL::Translator::Producer::XML::SQLFairy.
-This can lead to dramatic size savings.
