Subject cvs commit: jakarta-commons-sandbox/jelly/src/java/org/apache/commons/jelly/tags/core ImportTag.java CoreTagLibrary.java
Date Wed, 05 Jun 2002 18:03:38 GMT
werken      2002/06/05 11:03:38

  Modified:    jelly/src/java/org/apache/commons/jelly/tags/core
                        CoreTagLibrary.java
  Added:       jelly/src/java/org/apache/commons/jelly/tags/core
                        ImportTag.java
  Log:
  Added <jelly:import uri="location"/> which is semantically
  equivalent to <jelly:include uri="location" inherit="false" export="true"/>
  
  Like <include>, <import> allows the configuration of the 'inherit'
  attribute, which defaults to false.
