I now have the opportunity to expend my website into Arabic, but I have a major problem Western text is Left to right whereas Arabic is Right to left. When I copy the text sent to me in Arabic, it copies the text wrong. The template start as below...
Experimental h5 is non normative but still RTL is the value you'd use for the text direction. Regarding the META pragma directive it would be deemed 'obsolete' in h5, you could consider specifying the language on the root element instead. For example; HTML lang="ar" that should very loosely cover both questions posed regarding the markup aspect.
No, only the following: <meta http-equiv="content-language" content="ar"> would be obsolete since you cannot use that pragma (for the experimental h5). One alternative way would be use the lang attribute on the HTML root, resulting in: <html lang="ar" dir="rtl"> instead.
That's a Dreamweaver specific error with a DW template editable region (I don't have Dreamweaver installed or use it) to be balanced there has to be a #BeginEditable region and an #EndEditableRegion maybe you should create a new template loosely based on that one.
