Are Local Mode tags from 2.0 compatible with 2.4 local mode tags?

A Local Mode tag involves placing PHP code directly on your website and needs to be carefully handled.
Using 2.0 local mode tags with 2.4+ is fully compatible. However, if you are trying to use both a 2.0 local mode tag and a 2.4+ local mode tag on one page this can have complications.

It is recommended to use only 1 type of Local Mode tag on a single page.

All other 2.0 invocation tags should be fully compitible with 2.4+ tags, even when used on the same page.
