Editing .aspx/.ascx of precompiled web site (Project Portfolio Server Web Access)

[Handle]

I want to customize some aspx / ascx files of a precompiled site (the
project portofolio web access site). I have no access to source code.

Using Visual Studio, when I try to edit one these files in "design view", I
get the following two categories of errors:

1) Some "Cannot switch views" errors, like the following:

"Cannot switch views: This end tag has no matching start tag."
"Cannot switch views: Validation (XHTML 1.0 Transitional): Element '
myElement ' cannot be nested within element 'body'."
"Cannot switch views: Validation (XHTML 1.0 Transitional): Attribute 'align'
can be specified only once in a tag."

2) MANY "Element 'myElement' is not a known element.." errors, as:

"Element 'Benefits' is not a known element. This can occur if there is a
compilation error in the Web site"

In relation to registered user controls, like:
..
<%@ Register TagPrefix="WP" TagName="Schedule"
Src="../Parts/Projects/Schedule.ascx" %>
..
The web site I´m trying to customize is the Project Portfolio 2007 Web
Access (fresh install and working properly).

Using VS 2005 SP1, opening the site by using the "Open site" from "file"
menu.

These errors are related to the XML validation. Try changing the XML
validation from the context menu on the html code itself. Try changing
it to some older browser config. Hope this helps.

I disabled validation from "tools" --"options" -- it did not work.
