When I open an XML file in XMLmind, it assumes the dtd file is in the same

Not exactly. As mandated by the XML standard, it uses the system ID of
the DTD, whatever is this system ID.
Example: let's suppose your XML document starts with:
---
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE section PUBLIC "-//XMLmind//DTD Simple Section//EN"
"http://www.xmlmind.com/dtd/section.dtd";>
<section>
...
</section>
---
The public ID, that is, the formal name of the DTD, of the above DTD is:
-//XMLmind//DTD Simple Section//EN
The system ID, that is, the location of the DTD file, of the above DTD is:
http://www.xmlmind.com/dtd/section.dtd
This location can be relative or absolute. If relative, then it's
relative to the location of the XML document.
Is there a way to specific an ³include² path
and have it look there for the dtd for any XML file?
Yes, there is a standard mechanism for that called *XML* *catalogs*.

XML catalog for the above example:
---
<catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog"
prefer="public">
<public publicId="-//XMLmind//DTD Simple Section//EN"
uri="file:/C:/Users/charles/Documents/dtd/section.dtd"/>
</catalog>
---
Basically, the above XML catalog maps a public ID "-//XMLmind//DTD
Simple Section//EN" to an alternate, local, system ID
"file:/C:/Users/charles/Documents/dtd/section.dtd". (Notice the use of
URLs, not filenames.)
In order to deploy this catalog:
1) Copy the XML catalog file to any of the two addon/ folders scanned by
XMLmind XML Editor during its startup:
* XXE_install_dir/addon/
* XXE_user_preferences_dir/addon/ where XXE_user_preferences_dir/ is:
-----------------------------------------------------------
** $HOME/.xxe5/ on Linux.
** $HOME/Library/Application Support/XMLmind/XMLEditor5/ on the Mac.
** %APPDATA%\XMLmind\XMLEditor5\ on Windows XP, Vista, 7 and 8.
Example: C:\Documents and Settings\john\Application
Data\XMLmind\XMLEditor5\ on Windows XP.
C:\Users\john\AppData\Roaming\XMLmind\XMLEditor5\ on Windows Vista, 7 and 8.
If you cannot see the "Application Data" directory using Microsoft
Windows File Manager, turn on Tools>Folder Options>View>File and
Folders>Show hidden files and folders.
-----------------------------------------------------------
2) Click "Quick Start cache|Clear" in the "Options|Preferences" dialog
box, "Advanced|Cached data" section, to force XMLmind XML Editor to
rescan its two addon/ folders.

3) Restart XMLmind XML Editor.

XMLmind XML Editor configuration
--------------------------------
You seem to use XMLmind XML Editor without a configuration which would
teach XMLmind XML Editor how to cope with the type of XML documents you
edit.
XMLmind XML Editor is a below than the average XML editor, unless an
ad-hoc configuration has been developed for the type of documents being
edited.
Out of the box, we provide configurations for XHTML, DocBook and DITA.
There are also advanced configurations contributed by third-party
developers: Daisy, TEI, EAD, etc.
It's not difficult to write a simple configuration for your document
type. See "Writing a configuration file for XXE" --
http://www.xmlmind.com/xmleditor/_distrib/doc/configure/config_file.html
Of course, an XML catalog is often an integral part of even the simplest
configuration.
