Attr.IDPrefixLocal
TYPE: string
VERSION: 1.2.0
DEFAULT: ''
--DESCRIPTION--
Temporary prefix for IDs used in conjunction with %Attr.IDPrefix.  If you
need to allow multiple sets of user content on web page, you may need to
have a seperate prefix that changes with each iteration.  This way,
seperately submitted user content displayed on the same page doesn't
clobber each other. Ideal values are unique identifiers for the content it
represents (i.e. the id of the row in the database). Be sure to add a
seperator (like an underscore) at the end.  Warning: this directive will
not work unless %Attr.IDPrefix is set to a non-empty value!
