Via shorthand

Accessing attributes within the custom tag
If
testtwo.cfm
contains this CFML:
---custom tag ---<br>
<CFOUTPUT>#attributes.a# #attributes.x# #attributes.y#
#attributes.foo#</cfoutput>
<BR>--- end custom tag ---
Its output will be:
---custom tag ---
blab -X- 12 16
--- end custom tag ---
Executing Custom Tags
Tag instance data
During the execution of a custom tag template, ColdFusion keeps some data related to
the tag instance. The ThisTag scope is used to preserve this data with a unique
identifier. The behavior is similar to the File scope.
The following variables are generated by the ThisTag scope:
•
ExecutionMode — valid values are "start" and "end."
•
HasEndTag — used for code validation, it distinguishes between custom tags
that have and don't have end tags for ExecutionMode=start. The name of the
Boolean value is ThisTag.HasEndTag.
•
GeneratedContent — can be processed as a variable.
