- * NOTE on VF_TAG:
- *
- * Within uri-attributes, there is one problem: if you pass
- * an uri-attr to a macro or <$define>, the uri is parsed twice,
- * when attribute is passed to tag.
- * This produces shit when the uri is parsed the second time
- * (eg absolute uri is converted again)
- *
- * Therefor, uris are only parsed, if the VF_TAG-flag is
- * enabled. By default, VF_TAG is disabled and can only be
- * enabled when copying local macro attribute to the global
- * attribute list. (see "copy_local_varlist()" in "attrib.c")
