array parseSchemaFile ( mixed $filename, optional bool $returnSchema = FALSE )
Loads an XML schema from a file and converts it to SQL.
Call this method to load the specified schema from a file (see the DTD for the proper format) and generate the SQL necessary to create the database described by the schema.
If the optional parameter
$returnSchema is set to true, then the schema is returned rather than the SL statements.
In order to actually process the SQL statements, the returned array must be passed into the executeSqlArray method
