Considerations When Using Find Definition References
When you specify a definition name in an HTML area, it is not found using the Find Definition References menu item in Application Designer. It also won't be automatically renamed when a definition is renamed. All text within an HTML area is treated like a quoted string, a literal.
For example, Find Definition References won't find references to the PSLOGO image or the PT_EDITSCRIPTS HTML definition .
<img src='%Image(PSLOGO)'>
<script src='%JavaScript(PT_EDITSCRIPTS)'></script>
