Fully agree.

I have similar thoughts like James and therefore don't really see the need for it.
For the case to parse parts from an larger document the char[] can always be
converted to an InputStream to be used with 1).
But maybe your intention goes into another direction.

I propose to have a publicID.
E.g. the XML parser DXP supports public identifiers.

SGML/XML friendly "systemId" vs. Web-hacker-friendly "URI" as parameter name:
 I personally don't care to much about the name, both are appropiate.
 Maybe in a method with publicId the name "systemId" is better readable.
 Both names are fine as long as the are good described/documented
 (e.g. in the javadoc header in Java) to explain everybody the meaning.

The baseURI gives you all information to parse every relative
EntityReference correctly. What's still missing is the name of the
document where the parsing started. So this name will miss in
an error-message in the starting entity. 

So I propose to have:
 public abstract void parse (String publicId, String systemId, InputStream inputStream)
instead of 
 public void parse (InputStream is, String baseURI)
